  • route lan traffic through wirless mifi

    - by Randall Blake
    I have a Windows 7 laptop accessing the internet through Verizon wireless MIFI configured as 192.168.1.1. It supports only 5 wireless connections, so I don't want to use up connections unnecessarily. That laptop has an ethernet nic which I have given a static IP of 192.168.0.5. Everything else on the 192.168.0.0 network acquires an address via DHCP from a DLink router whose address is 192.168.0.1. Also on that network are a printer, some network cameras, and a linux pc. The linux pc does not have a wireless card (and I don't want to buy one). The linux pc is located at 192.168.0.122. I can ping the linux pc from the windows pc. But I cannot access the internet from the linux pc. I can ping everything on the 192.168.0.0 network EXCEPT the ethernet card in the Windows PC. It seems as though my DLink router will not route requests to the 192.168.0.5 nic on the windows pc. My windows pc has a default route pointing to the 192.168.1.0 network. It also has a route telling it to route all traffic destined for the 192.168.0.0 network through the 192.168.0.5 interface. I have tried adding a default route to the linux pc to "gateway" 192.168.0.5, but that does not work. I have also tried adding a default route to the linux pc to the gateway 192.168.0.1 (the DLink router) but that will not give me internet access either (over the 192.168.1.0 network). I tried these two different routes at different times - I did not set them both at the same time. I suppose this is a simple problem to solve, but I cannot seem to solve it. How can I give internet access over the 192.168.1.1 MIFI to my linux pc on 192.168.0.122? Thanks EDIT: Additional Info Internet | | MIFI (192.168.1.1) (wireless) | | (192.168.1.3) (wireless) Windows 7 PC Dlink Router (192.168.0.1) ------------ (192.168.0.5) (wired) | | |linux pc (192.168.0.122) (wired) | |printer (192.168.0.100) (wireless) | |network cameras, etc (192.168.0.103) (wireless) Only the windows pc is multi-homed with a wireless nic that connects to the MIFI wirelessly, and an ethernet nic with a wired connection to the DLink router. (The DLink permits both wired and wireless connections.) I don't want to use Windows internet connection sharing because I believe it will set up the ethernet nic as a gateway on 192.168.0.1 and a DHCP server. I already have the Dlink performing that role and I don't want to change that if I do not have to. (The Dlink permits me to make DHCP reservations and I really like that feature. I don't want to lose it.)

  • how to force an illegal netmask in ubuntu

    - by user1064232
    I want to force a netmask on my Ubuntu machine. For example, I want 11.0.0.1 to get a netmask of 255.255.255.0 I tried editing /etc/network/interfaces and I forced the desired netmask, but as soon as I restarted the interfaces it changed it back to the default value. When I used ifconfig the netmask that I gave survived the interface restart but it was reset as soon as I rebooted the machine. Is there a way to force an "illegal" netmask on an interface?

  • Changing Mac OS X 10.6 Routing after VPN'd In

    - by Matt Rogish
    I have a coffee shop around the corner that I use to do some work when I want to get away from home. They offer free wi-fi and I then use my Mac 10.6 VPN to log into my work network. I have "Send all traffic over VPN connection" checked. Before, their network was 10.0.0.x. I think they got a new router because it's now 192.168.2.x However, this interferes with one of the subnets at work so now I can't visit 192.168.2.x at work. So: 1) Office network: VPN gives IPs as 192.168.1.x. Another network is 192.168.2.x 2) Coffee network: Gives IPs as 192.168.2.x I think if I set a route to send all 2.x traffic over the tunnel, it would blow up my routing to their system, right? What should I do? I know the individual IPs of the servers I want... Maybe I could add each one, or can I add all of them minus the default gateway of their router? How do I set that up "temporarily" in my Mac? Thanks!!

  • Where do I learn about IP blocks and subnets? Or is there just a calculator that does it all for me?

    - by cwd
    Amazon's elastic compute tool (among others) requires the ip block format for their command: ec2-authorize websrv -P tcp -p 80 -s 205.192.0.0/16 I may be doing this wrong, but as far as I can tell I need to use the block format even for a single IP address. 1) So, how would I do that for this IP? 71.75.232.132 Several years ago I took a CCNA class, and I remember going over IPs and subnets, masks, broadcast addresses, class a/b/c networks, etc. However a lot seems to have changed since then - for example I don't think you can tell what "class" a network is in just by looking at it anymore - sometimes they could be multiple classes. 2) Anyhow, my second question is where do I go to get a refresher on all these things? 3) Or should I just be using ipcalc or an online calculator to do it all for me - and if so, which one?

  • One Comcast Business Gateway, One Router, Two Web Servers

    - by Kevin Scheidt
    I have a Comcast business account with a router and a web server (info) attached. behind the router there are multiple computers and a second web server (info) which also serves as a file server. (info) has two nics in it. One direct to comcast and one connected to the router. It needs to serve the world it's websites. It needs however, to also be able to see all the internal computers and (com)'s served files. With just 1 nic (the one connected to the router, not comcast), (info) works fine but no one outside can see it. (com) services port 80 and (info) needs to handle port 80 as well. I have two domain names registered, and 5 static ip's from comcast. right now h t t p: / /www.graceamazing.com handled by (com) works fine and h t t p: / /www.graceamazing.com:1307 handled by (info) works fine. but as soon as I enable the 2nd nic in (info) h t t p: / /www.graceamazing.info runs extremely slow (Horribly slow). however, h t t p: / /www.graceamazing.com:1307 and .com work fine. (com) has an ip address via the router 70.89.233.41 (info) has a ip addy of 70.89.233.46 via comcast (2nd nic) and a internal ip of 192.168.x.100 via static behind the router. Any suggestions or changes to make that will make h t t p: / /www.graceamazing.info perform with the same speed it has when going through h t t p: / /graceamazing.com:1307 is there a setting I should check / could have misssed?

  • subnetting a class c on a cisco 3825

    - by Adeodatus
    I have a class C that I want to better understand before I implement a change. Right now, ip address 192.168.0.1 255.255.255.192 ip address 192.168.0.65 255.255.255.240 secondary So, where is the 192.168.0.64 address in that mix? 192.168.0.63 should be the broadcast for the first one, and 192.168.0.65 should be the cisco secondary ip. And ... How then do I add a /28 (255.255.255.240) right before this segment: ip address 192.168.0.249 255.255.255.248 secondary In fact, I'll probably want to add it as a subinterface Can anyone help me to better understand whats going on and then how to do it?

  • Problem routing between directly connected Subnets w/ ASA-5510

    - by Zephyr Pellerin
    This is an issue I've been struggling with for quite some time, with a seemingly simple answer (Aren't all IT problems?). And that is the problem of passing traffic between two directly connected subnets with an ASA While I'm aware that best practice is to have Internet - Firewall - Router, in many cases this isn't possible. For example, In have an ASA with two interfaces, named OutsideNetwork (10.19.200.3/24) and InternalNetwork (10.19.4.254/24). You'd expect Outside to be able to get to, say, 10.19.4.1, or at LEAST 10.19.4.254, but pinging the interface gives only bad news. Result of the command: "ping OutsideNetwork 10.19.4.254" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.19.4.254, timeout is 2 seconds: ????? Success rate is 0 percent (0/5) Naturally, you'd assume that you could add a static route, to no avail. [ERROR] route Outsidenetwork 10.19.4.0 255.255.255.0 10.19.4.254 1 Cannot add route, connected route exists At this point, you might gander if its a NAT or Access list problem. access-list Outsidenetwork_access_in extended permit ip any any access-list Internalnetwork_access_in extended permit ip any any There is no dynamic nat (or static nat for that matter), and Unnatted traffic is permitted. When I try pinging the above address (10.19.4.254 from Outsidenetwork), I get this error message from level 0 logging (debugging). Routing failed to locate next hop for icmp from NP Identity Ifc:10.19.200.3/0 to Outsidenetwork:10.19.4.1/0 This led me to set same-security traffic permit, and assigned the same, lesser and greater security numbers between the two interfaces. Am I overlooking something obvious? Is there a command to set static routes that are classified higher than connected routes?

  • Subnetting design for a new building?

    - by Zombie
    A building with 4 floors, each floor is divided as follows; 15 users for accounting, 15 users for finance and 15 users for marketing (i.e 45 user in each floor). Data center is located on the ground floor, with 45 servers to be divided into 15 for all the accounting users in the four floors, another 15 for the finance and the last 15 for the marketing. (i.e each 15 server for each one of the above categories are separated from the other 15 and so on) What is the proper subnetting design for such scenario? Knowing that we are allowed to use anything we want!

  • Why is this static routing not working ?

    - by geeko
    Greeting gurus, I'm trying to develop a DHCP enforcement extension like Microsoft NAP. My trick to block dynamic-IP requesting machines (that don't meet certain policy) is to strip the default gateway (no default gateway) stated in the IP lease and set the lease subnet mask to 255.255.255.255. Now I need the blocked machines to be able to reach some specific locations (IPs) on the network. To allow for this, I'm including some static routes in the lease. For example, I'm including 10.10.10.11 via router 10.10.10.254 (the one to which the blocked machine that needs to access 10.10.10.11 is connected). Unfortunately, as soon as I set the default gateway to nothing, blocked machines cannot reach any of the added static routes. I also tried classless static routes. Any ideas ? any one knows how MS NAP actually do it ? Geeko

  • How host name is broadcasted in a subnet

    - by apalopohapa
    Hello. I'm working with Microchip's TCP/IP stack and the host name of my device is not being broadcasted, although I can access it using its DHCP assigned IP. So the question is, what is the protocol that a network device uses to broadcast its host name, so that when I see a list of devices in a network I can identify it by name? Is it the NetBIOS name service or something else? Thanks in advance.

  • Proper way to scan a range of IP addresses

    - by Josh G
    Given a range of IP addresses entered by a user (through various means), I want to identify which of these machines have software running that I can talk to. Here's the basic process: Ping these addresses to find available machines Connect to a known socket on the available machines Send a message to the successfully established sockets Compare the response to the expected response Steps 2-4 are straight forward for me. What is the best way to implement the first step in .NET? I'm looking at the System.Net.NetworkInformation.Ping class. Should I ping multiple addresses simultaneously to speed up the process? If I ping one address at a time with a long timeout it could take forever. But with a small timeout, I may miss some machines that are available. Sometimes pings appear to be failing even when I know that the address points to an active machine. Do I need to ping twice in the event of the request getting discarded? To top it all off, when I scan large collections of addresses with the network cable unplugged, Ping throws a NullReferenceException in FreeUnmanagedResources(). !? Any pointers on the best approach to scanning a range of IPs like this?

  • How do I get the IPv4 subnetmask on interface with both v4 and v6 address?

    - by Per Fagrell
    I have an InterfaceAddress that returns an ipv4 address (4 octets). However the network prefix length seems to be for the ipv6 address associated with the interface (it's returning as 128). How do I find the correct network prefix length? Enumeration<NetworkInterface> NetworkInterface.getNetworkInterfaces() for (; interfaces.hasMoreElements();) { final List<InterfaceAddress>interfaceAddresses = interfaces.nextElement().getInterfaceAddresses(); for (final InterfaceAddress address : interfaceAddresses) { assert(address.getAddress().getAddress().length == 4); // [sic] assert(address.getNetworkPrefixLength() < 32); // <- Fails. Actually equals 128 } }

  • Windows Server 2008: specifying the default IP address when NIC has multiple addresses

    - by Cédric Boivin
    I have a Windows Server which has ~10 IP addresses statically bound. The problem is I don't know how to specify the default IP address. Sometimes when I assign a new address to the NIC, the default IP address changes with the last IP entered in the advanced IP configuration on the NIC. This has the effect (since I use NAT) that the outgoing public IP changes too. Even though this problem is currently on Windows Server 2008 How can you set the default IP address on a NIC when it has multiple IP addresses bound? There is more explication on my probleme. Here is the ipconfig DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.99.49(Preferred) Subnet Mask . . . . . . . . . . . :

  • How can I determine which switch the Infiniband subnet manager is running on?

    - by ajdecon
    I recently inherited an Infiniband network containing multiple switches, and I know that one of these switches is running the subnet manager. The rest supposedly have that feature turned off, or were never enabled. The trouble is, I have no idea which one it is... I'd like to replace the switch subnet manager with OpenSM running on a couple of my infrastructure servers. Is there any way, short of logging into each switch individually, to determine which switch is running the SM?

  • Can I issue wireless clients with IP address on different subnet?

    - by Beanz
    We have a very standard setup with a Windows Server 2003 domain controller issuing IP addresses using DHCP. This works fine. Internet access is managed via Microsoft ISA Server 2006 Standard. Clients are required to authenticate and this works fine. We now need to provide wireless internet access to visitors for laptops, iPhones etc. We've bought a couple of Netgear access points so I was thinking we might be able to issue wireless clients connected to it with an IP address on a different subnet and then allow non-authenticated Internet access via the ISA Server for that IP range. Does that sound plausible? I'm not even sure if I can issue a different subnet to wireless clients.

    Is it possible to configure Bind9 or other DNS to resolve the domain name of a machine into different IPs based on the subnet of the requesting client? e.g. Say the same service is running on 2 different application servers at different geographical points and based on the incoming request to resolve the domain name, the name server provides the IP of the application server based on the requesting client's IP, so the service could be offered by servers that are geographically closer to the client. In short, something like a CDN but just the IP resolution part based on the client's subnet. Is this configurable in any DNS?

  • how can I stop my sonicwall TZ-210 (SonicOS Enhanced 5.5.1.0-5o) from responding to arp queries on the wan subnet?

    - by IsaacB
    My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway. How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately. What can I do? Any suggestions?

  • NAT and ISP Subnet when load balancing on pfsense?

    - by dannymcc
    I have a pfsense box that I'm trying to plan the configuration for. I am going to be load balancing two ISP's, each with their own /29 static IP subnet. The question I have is in relation to the way those IP's are associated with workstations on the local network. Currently I have some workstations with local (192.168.1.0/29) IP addresses, and other more complicated workstation setups have their own public IP address. Some of the more complicated systems have a NAT 1:1 configuration where I forward a public IP address to a local IP address. Others however are directly on the ISP subnet and cannot be seen on our local network. Is this configuration possible with pfsense? If so, what terms should I be looking through the documentation for? Here is a simple/brief diagram of what I am trying to achieve.

  • How to configure machines in a public subnet with two gateways?

    - by Shtééf
    We have a single public /24 subnet, with a BGP router as the primary gateway. Now I'm interested in configuring a second router for redundancy. How do I deal with multiple gateways on the servers in our public subnet? I found some other questions related to multiple gateways that seem to deal with NAT set-ups. In my situation, the servers all have public routed IP-addresses. So from what I can tell, it doesn't really matter which route incoming or outgoing packets take. But I figure the servers need some way of telling when one of the gateways is down, and route around it? Is this accomplished with protocols such as OSPF? And do I need to deploy this on all my servers?
