• Unable to PPTP through NAT on Cisco 881

  - by MasterRoot24

  I'm trying to connect to a PPTP server which is sat behind a Cisco 881 NAT router. The server is running Ubuntu Server 12.04 and is running Poptop pptpd as the PPTP daemon listening for connections. As discussed in my other question, I'm trying to setup a Cisco 881 router to replace my old Linksys WAG320N. This same server and WAN connection worked fine with the WAG320N with no special configuration, other than allowing 1723 in through the firewall. On the Cisco 881, I'm using the newer ip nat enable or NAT NVI to setup static routes in through the firewall for the services running behind the router. My reason being that I can't run another copy of my live DNS domains internally with local IP addresses in. For the purposes of this question, though, I have rebuilt the router with ip nat inside/outside style NAT'ing, but this issue is still apparent. HTTP/SMTP/IMAP etc. all work ok from both the WAN and LAN interfaces of the router. I'm only having issues with SIP (see other question) and PPTP. My issue is that the GRE doesn't appear to be passing through NAT correctly and one end of the connection is not receiving GRE traffic when it should be, so the server hangs up the connection. Here's an example of /var/log/syslog with debug enabled in /etc/pptpd.conf: Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: MGR: Launching /usr/sbin/pptpctrl to handle client Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: local address = 192.168.1.50 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: remote address = 192.168.1.51 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: pppd options file = /etc/ppp/pptpd-options Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Client 82.132.248.216 control connection started Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Received PPTP Control Message (type: 1) Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Made a START CTRL CONN RPLY packet Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: I wrote 156 bytes to the client.

Trying the connection to the LAN IP of the server from the same LAN as the server (behind the router), the PPTP connection works fine, so I'm confident that the server's config is ok. Furthermore, all I needed on my WAG320N was to open 1723 in the firewall. Here's my current router config: ! !

When attempting a connection, I can see in show ip nat nvi translations that both a TCP translation on 1723 is setup and also a GRE translation is setup also. I appear to be able to see GRE related packets on the LAN that the server is on, so I am lead to believe that the server is sending(?) GRE packets, however running Wireshark on a client PC when attempting a connection shows absolutely no GRE packets. Whilst there are no configuration directives in my config posted above (that I can pin point) which would specifically block them, it would appear that the GRE packets are not being allowed in/out of the router's firewall, even though a NAT translation entry is setup to the server's LAN address. Would anyone be able to provide me with some help to ensure that GRE packets are not blocked by the router's firewall, so that this can be ruled out as a possible issue please?

• ASA5500 series logging for management interface in transparent mode

  - by ANervousTwitch

  i have a cisco asa5520 in transparent mode. the interface is on the same subnet as some windows machines, which are generating a lot of broadcast traffic that is filling up the logs. is there any way to have it not log that its blocking those packets? its a bunch of these messages: "through-the-device packet to from management-only network is denied: udp src..." im also seeing some of those zeroconf requests that id like to drop logging for. i tried to just put a rule on the management interface, but apparently thats not allowed.

• Multiple Set Peer for VPN Failover

  - by Kyle Brandt

  I will have two Cisco routers at Location A serving the same internal networks, and one router in location B. Currently, I have one router in each location with a IPSec site-to-site tunnel connecting them. It looks something like: Location A: crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location B set peer 12.12.12.12 set transform-set ESP-3DES-SHA match address internal-ips Location B: crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location A set peer 11.11.11.11 set transform-set ESP-3DES-SHA match address internal-ips Can I achieve fail over by simply adding another set peer at location B?: Location A (New secondary Router, configuration on previous router stays the same): crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location B set peer 12.12.12.12 set transform-set ESP-3DES-SHA match address internal-ips Location B (Configuration Changed): crypto map crypto-map-1 1 ipsec-isakmp description Tunnel to Location A set peer 11.11.11.11 ! 11.11.11.100 is the ip of the new second router at location A set peer 11.11.11.100 set transform-set ESP-3DES-SHA match address internal-ips Cisco Says: For crypto map entries created with the crypto map map-name seq-num ipsec-isakmp command, you can specify multiple peers by repeating this command. The peer that packets are actually sent to is determined by the last peer that the router heard from (received either traffic or a negotiation request from) for a given data flow. If the attempt fails with the first peer, Internet Key Exchange (IKE) tries the next peer on the crypto map list. But I don't fully understand that in the context of a failover scenerio (One of the routers as Location A blowing up).

• cisco 2911 router vs 2811 router

  - by NickToyota

  Just wondering if anyone has experience with the cisco 2911 or 2900 series routers. I understand it is newer and similar to the 2811 but more robust. The price difference is not that much more. I am trying to determine if I should go with the 29xx or 28xx series for a small-medium sized company. ISP bandwidth load balancing and fail over is required. T1 and ADSL lines already in place.

• What is the equivalent of Cisco's 'ip virtual-reassembly' for a Juniper ISG 2000

  - by 2xyo

  I tested my dns servers with the oarc test and my size limit is at least 1403 bytes. I performed the same test before my Juniper ISG 2000 and the result is 2047 bytes. According to the chapter IP "Fragments Filtered" and this article, I think I have a fragmentation problem. This article talks about ip virtual-reassembly for cisco but I can't find the equivalent for Juniper. I prefer to find the good option in JunOS before I talk about this with my net admin :-) Thanks

• Configuring Cisco 3800 ISR Router with two default gateways for different subnets

  I am trying to configure two physical interfaces on a Cisco router to act as two separate gateways for two different subnets: gigabitEthernet0/0 gw 10.10.10.10 255.255.0.0 for network 10.10.0.0 gigabitEthernet0/1 gw 10.15.10.10 255.255.0.0 for network 10.15.0.0 Should I be using rip version 2 routing or can I just use static routing to do this?. If you can provide an example for doing this, I would be very appreciative.

  I have a cisco 861 router that only allows one-to-one NATs in order to access the Internet. I would like for computers to get an address via DHCP from this router, and be able to access the Internet without needing to set a static NAT to one of my public IPs. What is wrong with the configuration? I have a basic understanding of the IOS CLI, most of the configuration file (edited for content) was created by my company's long gone Senior Network Engineer.

• Cisco Anyconnect Issue on HTC HD2

  Hello, We've just got a HTC HD2 handset through (UK - T-mobile); and we've installed the Cisco Anyconnect client. It connects ok but then after a few seconds disconnects, then reconnects. It then keeps cycling through in this way, and at no point can we even attempt to sync Exchange! Our ASA 5510 reports; Group User IP <149.254.217.2 SVC Message: 17/ERROR: Reconnecting to recover from error..

service-policy global_policy global prompt hostname context The servers that had static forwards did not have any outside network access. couldn't ping google.com for instance. mail server couldn't Domain POP the Barracuda spam filter from our ISP etc. So after doing some reading I removed the statics for 172.21.37.11, 12 and 13, and replaced those three with what's below.. static (inside,outside) tcp 321.321.39.11 https 172.21.37.14 https netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.11 993 172.21.37.14 993 netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.11 smtp 172.21.37.14 smtp netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.11 1001 172.21.37.14 1001 netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.11 465 172.21.37.14 465 netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.11 domain 172.21.37.14 domain netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.12 www 172.21.37.24 www netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.12 https 172.21.37.24 https netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.13 www 172.21.37.17 www netmask 255.255.255.255 static (inside,outside) tcp 321.321.39.13 https 172.21.37.17 https netmask 255.255.255.255 Now the servers (for instance 172.21.37.14) could ping the outside world again. Mail started flowing (Domain POP was successful) etc. etc. But I forgot to check if webmail worked from the outside admittedly. But the webservers at 172.21.37.17 and 172.21.37.24 still didn't respond from the outside world. Although I was able to PPTP VPN in on 321.321.39.10 (interface) which is the outside interface IP address. and it is static mapped to 172.21.37.20. So I'm thinking there must be something wrong with NAT somewhere? no response from 321.321.39.11 to 321.321.39.14.. Could anyone look over the config and please let me know what I've done wrong? Is there something I've missed? well obviously but.. please help! Thank you.

• Cisco VPN error 403: Unable to contact the security gateway

  - by mtashev

  I'm trying to make a connection via Cisco VPN Client (version is 5.0.07.0290), but i get the below mentioned error. I have to say that i'm using Windows 8. "Secure VPN Connection terminated locally by the Client. Reason 403: Unable to contact the security gateway." I've tried several fixes, but none of them worked. The display name in regedit is the correct, and my certificates are ok as well. If i switch to TCP (the default is UDP) i get error 414. Firewall is off. Any suggestions will be appreciated.
