  • Unable to access internal network through PfSense WAN port

    - by Sean
    Our branch office is unable to connect to our internal network for some reason. However we can connect to the branch office domain controller from behind PfSense. The following is our setup: |Branch DC - 192.168.0.101 | |Branch Firewall - 192.168.0.2 | |(Internet) | |Local Firewall - 192.168.3.1 | |PFSense WAN port - 192.168.3.100 |PFSense LAN port - 192.168.1.1 | | DC1 - 192.168.1.2|DC2 - 192.168.1.4 Branch DC can ping and connect to PFSense WebGUI on the WAN port successfully (we set this up using the PfSense documentation). DC1 and DC2 can connect outbound to the Branch DC. There seems to be a rule that prevents internal access on the WAN port. However our rules are set to allow all traffic on the LAN and WAN ports. It would be ideal to just disable the firewall altogether since we already have a firewall but when we do this, PfSense doesn't allow any internal traffic at all. I look forward to any assistance and thank you ahead of time.

  • Connecting a LAN to an OpenVPN server via a windows 7 client gateway

    - by user705142
    I've got OpenVPN set up between my windows 7 client and linux server. The goal is that I'll get secure access to a webapp running on the server from any computer on the client LAN. I'm using ccd to assign static ip addresses to each client connection, with key authentication. It's working on my client machine (10.83.41.9), and when you go to the gateway IP address (10.83.41.1), it loads up the webapp. Now I really need the other computers on the client LAN to be able to connect to the webapp as well, via the windows machine. The client has a static IP address of 192.168.2.100 on the LAN, and I've enabled IP forwarding in windows (confirmed by ipconfig /all). In my router I've forwarded 10.83.41.1 / 255.255.255.255 to 192.168.2.100. In server.conf I have.. route 192.168.2.0 255.255.255.0 And in the office ccd.. ifconfig-push 10.83.41.9 10.83.41.10 iroute 192.168.2.0 255.255.255.0 The client log is as follows: Thu Mar 15 20:19:56 2012 OpenVPN 2.2.2 Win32-MSVC++ [SSL] [LZO2] [PKCS11] built on Dec 15 2011 Thu Mar 15 20:19:56 2012 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Thu Mar 15 20:19:56 2012 Control Channel Authentication: using 'ta.key' as a OpenVPN static key file Thu Mar 15 20:19:56 2012 Outgoing Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Incoming Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 LZO compression initialized Thu Mar 15 20:19:56 2012 Control Channel MTU parms [ L:1558 D:166 EF:66 EB:0 ET:0 EL:0 ] Thu Mar 15 20:19:56 2012 Socket Buffers: R=[8192->8192] S=[64512->64512] Thu Mar 15 20:19:56 2012 Data Channel MTU parms [ L:1558 D:1450 EF:58 EB:135 ET:0 EL:0 AF:3/1 ] Thu Mar 15 20:19:56 2012 Local Options hash (VER=V4): '9e7066d2' Thu Mar 15 20:19:56 2012 Expected Remote Options hash (VER=V4): '162b04de' Thu Mar 15 20:19:56 2012 UDPv4 link local: [undef] Thu Mar 15 20:19:56 2012 UDPv4 link remote: 111.65.224.202:1194 Thu Mar 15 20:19:56 2012 TLS: Initial packet from 111.65.224.202:1194, sid=ceb04c22 8cc6d151 Thu Mar 15 20:19:56 2012 VERIFY OK: depth=1, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 VERIFY OK: nsCertType=SERVER Thu Mar 15 20:19:56 2012 VERIFY OK: depth=0, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 Replay-window backtrack occurred [1] Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA Thu Mar 15 20:19:56 2012 [server] Peer Connection Initiated with 111.65.224.202:1194 Thu Mar 15 20:19:58 2012 SENT CONTROL [server]: 'PUSH_REQUEST' (status=1) Thu Mar 15 20:19:59 2012 PUSH: Received control message: 'PUSH_REPLY,route 10.83.41.1,topology net30,ping 10,ping-restart 120,ifconfig 10.83.41.9 10.83.41.10' Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: timers and/or timeouts modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: --ifconfig/up options modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: route options modified Thu Mar 15 20:19:59 2012 ROUTE default_gateway=192.168.2.1 Thu Mar 15 20:19:59 2012 TAP-WIN32 device [OpenVPN] opened: \\.\Global\{B32D85C9-1942-42E2-80BA-7E0B5BB5185F}.tap Thu Mar 15 20:19:59 2012 TAP-Win32 Driver Version 9.9 Thu Mar 15 20:19:59 2012 TAP-Win32 MTU=1500 Thu Mar 15 20:19:59 2012 Notified TAP-Win32 driver to set a DHCP IP/netmask of 10.83.41.9/255.255.255.252 on interface {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} [DHCP-serv: 10.83.41.10, lease-time: 31536000] Thu Mar 15 20:19:59 2012 Successful ARP Flush on interface [45] {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} Thu Mar 15 20:20:04 2012 TEST ROUTES: 1/1 succeeded len=1 ret=1 a=0 u/d=up Thu Mar 15 20:20:04 2012 C:\WINDOWS\system32\route.exe ADD 10.83.41.1 MASK 255.255.255.255 10.83.41.10 Thu Mar 15 20:20:04 2012 ROUTE: CreateIpForwardEntry succeeded with dwForwardMetric1=30 and dwForwardType=4 Thu Mar 15 20:20:04 2012 Route addition via IPAPI succeeded [adaptive] Thu Mar 15 20:20:04 2012 Initialization Sequence Completed From the other machines I can ping 192.169.2.100, but not 10.83.41.1.

Ideally this would be achieved without any special configuration the other LAN computers. Not sure how far I'm going to get on my own at this point, any ideas? Is there something I'm missing, or anything I should need to know?

  • How to load tun module in linux?

    - by rabipelais
    I cannot manage to load the tun module in my archlinux box. I'm trying to connect with openvpn, but the log says nm-openvpn[6662]: Note: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19) lsmod | grep tun returns nothing. If I run sudo modprobe tun it returns failure, but no error message, and lsmod still has no tun. The module seems to exist, as there is a tun.ko.gz in /lib/modules/....... I really dont know what else to try. Thanks in advance

  • how to connect public web server to internal LAN

    - by DefSol
    I have a VPS which is my public web server for all my clients. It's running server 2008 and I would like to have it connect via secure connection to my internal LAN. I would like this to be a route so access is bi-derectional. Have read about Server & Domain isolation, but am concerned this may prevent public views to the webs sites on the server. I currently have a PPTP tunnel, but I'm wanting better security (IPSec or SSL etc) and it's not given my bi derectional access. (In fact my backups aren't copying accross but this could be an acl issue) The goal is to provide easy/automated backups of data & sql db's to my internal LAN, as well as a means to provision new sites & db's from a workflow occuring internally. Internal lan is windows based with ISA 2006 at the perimeter. Thanks

  • OpenVPN to connect remote networks, peer to peer instead of client/server possible?

    - by John Robertson
    I would like to connect two remote networks using OpenVPN. I am very new to this we are very small and don't have a sys/network admin. What are the possible setups to have both networks both live on a common LAN via OpenVPN? I would prefer to use the UDP peer model rather than client/server. Is there a way to set that up instead? I can't see how because no computer on existing network A has a routable address to any computer on existing network B and vice versa.

  • A Linux DHCP server that will listen on an non-broadcast (tap) interface?

    - by TomOnTime
    Are there any Linux DHCP servers that will listen to what Cisco calls an "unnumbered" interface, or what others might call a "NBMA" (non-broadcast) interface. I have a Linux system that connects to a number of others using GRE tunnels. The machines on the other end send DHCP requests to this machine, I can see them with tcpdump. However, ISC DHCP 3.0.3 refuses to listen to the interface because it is non-broadcast. The interface I'd like DHCP to listen to is: tap2 Link encap:Ethernet HWaddr removed-for-privacy inet6 addr: removed-for-privacy/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:518 errors:0 dropped:0 overruns:0 frame:0 TX packets:510 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:196242 (191.6 KiB) TX bytes:52425 (51.1 KiB)

  • Seemingly random network connectivity.

    - by AngryHacker
    This has been driving me nuts for a while. When I turn on the PC (which has a wired Ethernet connection), it cannot be accessed by other computers on the network. In other words, inbound connections do not work. The firewall is disabled. The PC itself can hit up anything it wants just fine. By process of elimination, I've figured out that checking or unchecking the Eaclift driver in the properties for my network connection restored the inbound connection. I do not know what Eaclift driver is or does or how it even got on my PC (e.g. I am not allowed to uninstall it either). And it does not matter whether it's on or off - I just need to toggle it to restore connectivity. One other thing that happens when I toggle the Eaclift driver, is than an Internet Connection icon appears in the Network Connections and it was not there before. Can someone shed some light as to what is going on? How to fix it so that I don't have to deal with this insanity?

  • Iptables mark incoming packet - vpn routing

    - by Tom
    I have connected my home to my workplace for out of house backup reasons through openvpn. The connection is working nicely. At work I have 5 fixed IP addresses. Now I would like to assign one of these IP addresses to be forwarded to my home machine. I have confirmed packet arrival at my home machine with tcpdump. The problem is that my default route at home is NOT the tun0 (naturally), but eth0 to my own ISP. So I created a separate routing table to route my tun0 packets back to where they belong, but do not how to mark the incoming packet which arrive through tun0 with iptables, so I can drive them back. I do not want any port restrictions, but only what comes from tun0 should leave through tun0 thanks tom

  • Server 2003 RAS Server Utilising High WAN Traffic

    - by Joe Sergeant
    We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

  • How do I troubleshoot an IPsec tunnel (from a cellular router to a public server)?

    - by Hanno Fietz
    I'm new to IPsec and struggling with a setup that might soon be widely used in our operations (provided I do understand it, eventually...). A cellular router (blackbox by netModule, from its log messages it seems to be running Linux and OpenSwan) connects a sensor network on customers' sites with our public server. We need to be able to connect into the local network, so I had the cell provider give me a public IP (a dynamic one). The way their setup works, the public IPs only allow IPsec traffic. I set up OpenSwan on our Ubuntu server (running Jaunty). This is my connection config from /etc/ipsec.conf: conn gprs-field-devices left=my.pub.lic.ip [email protected] #leftsubnet=192.168.1.129/25 right=%any [email protected] #rightsubnet=192.168.1.1/25 #rightnexthop=%defaultroute auto=add On the router, all I have is the Web UI, in which I made the following settings: "Remote endpoint": public IP of server, same as "left" above "Local Network Address": 192.168.1.1 "Local Network Mask": 255.255.255.128 "Remote Network Address": 192.168.1.129 "Remote Network Mask": 255.255.255.128 The pluto process on the server is listening for connections on port 500. It can't open a tunnel, obviously, because it doesn't know at which IP the client is. I set up a passphrase as PSK for @field.econemon.com in /etc/ipsec.secrets and also configured it in the router (which doesn't seem to support certificates). My problem is, nothing happens. The router just says, IPsec is "down". When I copy-paste the IP into ipsec.conf (for "right="), and ask the server to ipsec auto --up gprs-field-devices, it just hangs until I press Ctrl-C. Is there anything wrong with my setup? How can I debug this further? My router gives the following loglines that seem related, but don't tell me anything: Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/hostkey.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/netbox0.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: "netbox00" #1: initiating Main Mode Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: 104 "netbox00" #1: STATE_MAIN_I1: initiate Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: ...could not start conn "netbox00" Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: received and ignored informational message Feb 21 23:08:28 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 0 seconds Feb 21 23:08:40 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 10 seconds Feb 21 23:08:52 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN

  • Work from home on an iPad?

    - by Alex Basson
    The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!

  • Tunneling a public IP to a remote machine

    - by Jim Paris
    I have a Linux server A with a block of 5 public IP addresses, 8.8.8.122/29. Currently, 8.8.8.122 is assigned to eth0, and 8.8.8.123 is assigned to eth0:1. I have another Linux machine B in a remote location, behind NAT. I would like to set up an tunnel between the two so that B can use the IP address 8.8.8.123 as its primary IP address. OpenVPN is probably the answer, but I can't quite figure out how to set things up (topology subnet or topology p2p might be appropriate. Or should I be using Ethernet bridging?). Security and encryption is not a big concern at this point, so GRE would be fine too -- machine B will be coming from a known IP address and can be authenticated based on that. How can I do this? Can anyone suggest an OpenVPN config, or some other approach, that could work in this situation? Ideally, it would also be able to handle multiple clients (e.g. share all four of spare IPs with other machines), without letting those clients use IPs to which they are not entitled.

  • Using VMware Guest OS to enable Host OS to ssh to remote network

    - by Reuben L.
    Basically I have an issue because my host OS is 64-bit Linux Mint (Ubuntu derived) and it doesn't seem to be compatible with the Juniper Network Connect that is used by the network at my workplace. Thus, I am unable to ssh from terminal to the network. I can't make changes to the workplace network either so that leaves me with looking for solutions on my end. The main reason for me to access the network from home is to check on my running processes or to issue more commands to a few workstations. Putty is the desperate choice I usually make but it means I have to reboot to Windows and also have limited control. I've tried several other methods and they have all failed. Recently, I setup a VM with Windows 7 as the guest OS. Now half my problems are fixed as I don't have to physically reboot the system - I just have to engage Juniper Network Connect on the VM. However, I would still like to use my Linux terminal to ssh to the network. It sounds plausible that I could somehow manipulate ports to connect to the remote network from the host OS tunneled through the guest OS, but I really have no clue how to do so... Can anyone help?

  • Browsing \\computer\share fails, but net use \\computer\share works?

    - by JMD
    I've had mixed results with using Windows Explorer to browse remote file shares. The setup: I'm at work on Windows XP SP3 Files are at home on Windows XP SP3 Two separate VPNs are available to access my PC at home corporate OpenVPN (10.1.2.3) a Hamachi/LogMeIn connection (5.1.2.3) With respect to my problem, it doesn't matter which IP I use. They both perform exactly the same way: I expect that if I open Windows Explorer and type in \\10.1.2.3\Shared I should be interrupted with a challenge for credentials, and then be able to interact with the files in the share. However, I just get that annoying dialog, "Windows cannot find '\10.1.2.3\Shared' Check the spelling and try again, or try searching for the item ..." However, I can take that exact same computername/sharename and with net use I can: net use * \\10.1.2.3\Shared * /user:homecomputername\username with this result: Type the password for \\5.69.83.158\C$: Drive Z: is now connected to \\5.69.83.158\C$. The command completed successfully. I can then access the files in Z: in Windows Explorer which was my original intent. Even after Z: is already mapped and the credentials are cached I still cannot bring up \\10.1.2.3\Shared in Windows Explorer. Why does the latter work, but not the former? Edit: Other services work fine, such as RDP. (I have a problem in which I can't SSH home, but I'll consider that separately.)

  • OpenVPN multiple servers on the same subnet, high availability

    - by andre
    Hey everyone. Let me start by saying that my Linux experience isn't super awesome but I can usually find my way around things easily. Over at work we have an OpenVPN setup that's been due for some improvement for a while now. The main server (tap mode) runs in our office, behind a rather slow DSL connection. The main problem is that, since I'm usually out of the office, every time I want to access something on the virtual network I have to go through that server to get anywhere else. We have two servers up on 100 Mbit connections that we use for development and production purposes, about 3 more servers in the office (one of them behind a different T1 line for VOIP) and about two dozen clients who use the network on a daily basis from various locations. We've had situations where network routing (outside of our control) would not allow people to reach our main OpenVPN server whilst the other locations were connectable. Also any time someone outside the office wants to fetch something from any of the servers (say, a 500 MB code repository), a whopping 20 KB/s download speed is just unacceptable these days (did I mention slow DSL? ok). We had to implement traffic shaping on this server since maxing out this connection was fairly trivial. I had the thought of running two (or more) OpenVPN servers in the network. These would have to have the same subnet though, as our application relies on virtual network's IP addresses for some of its core functionality. The clients would also preferably retain the same IP addresses but that's not vital. For simplicity, lets call the current server office and the second server I'm setting up, cloud. Call the server on the T1 phone. This proved to be rather complex because as soon as I connect to cloud, I cannot see office. Any routes to a server that would go through office also do not work while I'm connected to cloud (no ping, nothing) and vice-versa. There's no rules for iptables that would be blocking the traffic either. Recently I came across this article on linuxjournal but the solution they provide seems to only cover the use of two servers and somewhat outdated (can't even find much documentation, their wiki is offline). They also state that adding more servers would be a complex task. Ideally I would like to keep the existing server office running the virtual network and also run the OpenVPN daemon on the cloud and phone servers (100 Mbit and very reliable connection, respectively) so that we're on safe ground in case of a hardware failure, DSL failure, etc. So, in essence, I'm looking for a highly available OpenVPN solution (fix, patch, hack, tweak, whatever you want to call it) that will accept connections on multiple hosts (2 or more) whilst keeping the same IP address subnet regardless of the server to which you connect to. Thanks for reading and sorry for the long post, I hope it gets the point across :P

  • L2TP and multiple interfaces on the machine

    We have setup ipsec and l2tp on linux. One question came up (due to firewall management policy) is whether it's possible to have 1 virtual interface instead of one per connected client. Now we have: ppp0 serverip clientip1 ppp1 serverip clientip2 Want to have: l2tp_tun serverip serverip like with OpenVPN's tun interfaces and then to be able to push IP address and route to each client.

  • OpenVPN Permission Denied Error

    - by LordCover
    I am setting OpenVPN up, and I'm in the state of adding users. Details: Host System: Windows Server 2003 32-bit. Guest System: Ubuntu Linux (with OpenVPN installed already), actually I downloaded it from OpenVPN.Net. Virtualization: VMWare v7.0 Problem: I can access the Access Server web portal (on the port 5480), but when I login to http://host_ip:943/admin and enter my (correct) login info, it shows me a page saying that "You don't have enough permissions". I am the (root) user!!!! that is really weird!!! Note: if I enter wrong login it will denote an incorrect login, this means that I am logging in successfully but the problem comes after the login process. What I tried: I tried to create another user after (root) logging in to Linux Bash using (useradd) command, but the same resulted.
