Cisco VPN :: 1841 / Site To Site Vpn Not Working?
Apr 24, 2012
i have 2 routers both 1841's and am trying to get a simple static vpn up and running. Now One router is at our main location (ill call it router a) and the remote location (ill call it router b). Both have internet connectivity that works, can ping router a from b and b to a. Now on router b side when i run show crypto isakmp sa on router b i get the following:
SBOneonta#show crypto isakmp sa
IPv4 Crypto ISAKMP SA
dst src state conn-id status
72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted)
72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted)
72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted)
[code]....
i72.43.229.138 is the router and the other ip is i have no idea! its no where in the config, but that shows me this router is trying to do something. Now on router a when i run the same command i get this:
show crypto isakmp sa
dst src state conn-id slot status
a whole lot of nothing! now i have been working on this for a few days now and i cant understand why i cant get this simple vpn tunnel to work! I have debuging on both routers, router a shows nothing period for vpn traffic, router b shows a connection from the 66.194.51.66 which again i have no idea who or where this ip is and its not in the config any where.

The problem I am having is very strange and I have tried to upgrade the IOS on the 1841 to solve the problem but no luck. The issue is when I enable Zone Based firewall security on of the 1841 routers two VPN site-to-site tunnels stops working. If I turn off CEF (no ip cef) then the traffic for both tunnels works. Someone told me that the Zone Based firewall must have a match for the VPN traffic and I created that with ACL 160 and 161 but it did not solve the problem.
Current IOS is below.
Cisco IOS Software, 1841 Software (C1841-ADVSECURITYK9-M), Version 15.0(1)M9, RELEASE SOFTWARE (fc1)

Using the Cisco Configuration Professional software I have created a site to site VPN connection (between a cisco 1841 and 1811).The tunnel appears to be up as far as the routers are concerned, but I am unable to ping anything on the remote networks. I thought route maps may have had something to do with this but I cant see what is worng with them.Just so you know, the 1841 device already has a functioning VPN tunnel to another site. The peers I am concerned about are 141.0.59.x and 109.238.78.x.

I am in the process of setting up a site to site VPN connection with a Cisco 1841 with the AIM-VPN-SSL-1 module and an NEC IX2015. We are using a GRE tunnel with IPSec.The problem we are having is the NEC router will not repsond to ICMP packets (and there isn't a way to make it respond). Will this cause any problems with the tunnel?

Is there a guide to set up a site to site VPN using 1841.
I have 3 points, 1 1841, 1 pix 506e and 1 ASA 5500. I need a good guide/manual to set up this. I would like to connect to any of the points, and be able to see all the infrastructure.

I have an 1841 that I set up to do site to site VPN between my company's network and an external network. This has a backup connection point. All works well including automatically failing over to the backup site.
We also want to be able to VPN remotely to our company's network using the same 1841.I have tried many different ways to configure this, but the best I had resulted in an external VPN request taking down the site-to-site link.
Is this possible? Our internet connection is through an ADSL router set up with pasthrough, then into the Cisco 1841 which does the dialer PPPOE authentication.

How many site-to-site VPN can we establish in Cisco router 1841. When we start 1841 we get the message that VPN Module 1. What is the meaning of it, does it mean that we can establish only one VPN. How about the limitation of GRE VPN Tunnel.

he IPSec tunnels do not form and I notice the error: 3Aug 09 201105:13:26IP = 39.188.41.188, Error processing payload: Payload ID: 1 Reading up on this it looks like it might be an IKE problem but I'm struggling to find the cause (the new 8.4 commands not useful).
The setup is as follows:-
Head Office
PIX515e v6.3(4)
LAN IP 10.0.160.254/24
Branch Office
ASA5505 v8.4(1)
LAN IP 192.168.47.254/24

I have an ASA 5505 and a 5510 that had a VPN connection working until the external ip address of the 5510 changed. I deleted the existing VPN connection on the 5505 and recrerated it with the new address of the 5510. I can see that the vpn lin is established, but the 5505 isn't transmitting any bytes. I looked in the Monitoring > VPN > VPN Statistics > Sessions and I see that the link is established and the bytes Rx is working, but the bytes Tx stays at 0 (this is on the 5505, on the 5510 there are no Bytes Rx, but there are bytes Tx). I don't think the problem is with the 5510, because that router has a vpn connection to another 5505 which is working fine.
config for the 5505 where the VPN isn't working: The VPN in question is the one with the ip address 207.229.xx.xx the other VPN (208.118.xx.xx is working, but is no longer needed) [code]

I have a 5505 connected to 5510 via a site to site VPN, the vpn has 5 subnets on the acl list at both ends, but 2 of the subnets are assigned for remote access on the main 5510, which means the flow of traffic on these 2 subnets are main to remote, but the VPN only works if the traffic starts from remote to main.
both sides are set to bidirectional and I'm not sure if this is the case for all 5 subnets has remote site always sends data to the other 3 subnets first.

I have a network of 5 different ASA 5505 they are all connected via site to site VPNs. 4 of the routers are working fine but the 5th one is only connecting to 2 VPNs when it should be connecting to 4 VPNs. I have verified that all the settings are correct on the routers (peer ip address, PSK, etc...) but the router still only connects to 2 VPNs. Is this a licensing issue? The license of the router in question looks like this: [code]

We have 2 ASA's that connect to a 2811, but for some reason, the 2nd ASA wont connect anymore. Debuging ipsec or isakmp on the 2811 doesn't come up with any messages.
External IP's still correct, and the sites can ping each other.
Only debug on ASA for crypto isakmp comes up with messages (ipsec doesn't give any messages).
ASDM says:
Removing peer from peer table failed, no match!
Error: Unable to remove PeerTblEntry
I found some info on the above error messages, but those links didn't quite useful.
Below is fromt he debug on the ASA:
Sep 18 22:06:09 [IKEv1 DEBUG]: Pitcher: received a key acquire message, spi 0x0Sep 18 22:06:09 [IKEv1]: IP = 64.X.X.X, Queuing KEY-ACQUIRE messages to be processed when P1 SA is complete.Sep 18 22:06:10 [IKEv1 DEBUG]: Pitcher: received a key acquire message, spi 0x0Sep 18 22:06:10 [IKEv1]: IP = 64.X.X.X, Queuing KEY-ACQUIRE messages to be processed when P1 SA is complete.Sep 18 22:06:13 [IKEv1 DEBUG]: Pitcher: received a key acquire message, spi 0x0Sep 18 22:06:13 [IKEv1]: IP = 64.X.X.X, Queuing KEY-ACQUIRE messages to be processed when P1 SA is complete.Sep 18 22:06:16 [IKEv1]: IP = 64.X.X.X, IKE_DECODE RESENDING Message [code]...

I'm experiencing troubles in setting up a simple site-to-site VPN between two new ASA 5505. I tried several times with the ASDM tool entering configuration manually or using the wizard, resetting every time to factory defaults, but the tunnel wont work.

I have two 871 routers and I can't seem to get the site to site VPN working between them. When I do a site to site test connection I get this error: there is no response from peer 208.38.11.xx when I try to ping that ip address from the cisco I get no reply. My site and the peer site are on the same ISP and this isp has had problems in the past where two nodes on the same network couldn't communicate with each other. So before I spend two hours on hold with this isp I want to make sure that the prblem is not with the cisco configurations. Here are the running configs:
Host A:

AT site A, I have Vlan's 652-10.55.216.0/24, Vlan653 -10.55.217.0/24, Vlan 654-10.55.217.0/24 and Vlan655-10.55.219.0/24 and at site B, Vlan650-10.55.214.0/24 and Vlan651-10.55.215.0/24.The problem is that I am unable to get any associations when i do a "sh crypto isakmp sa"/"sh crypto ipsec sa" on either router at each site.I am also unable to ping by pluging in a laptop into the site at each site. Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.

Our Headquarter (asa 5510) is running a site to site vpn connection with a Branch office (router 2811). All remote users are accesing the internet through the VPN and also accesing headquarter file servers.I want to know if there is a way for some remote users to be able to use the vpn for accesing the file servers but to access the internet through the branch office. The rest of the remote users will be still accessing the internet through VPN.

We've just deployed a site-to-site VPN using a 5505 ASA on the client's site and a checkpoint Nokia FW on our site. Everything seems to be fine except that the user's connections to their file shares seem to be intermittently dropping. One minute the connection to the shares is there, next thing it's lost. There is no logic to it because no two users are experiencing issues at the same time, as a matter of fact even on the same PC where a user has access to 3 shares on 3 different servers, one could be showing as connected whereas the other two be dropping. [code]
As you can see the Duplex and Speed are set to auto, I've rectified this since then and I'm keeping a close eye on the output errors, and collisions. However, I'm afraid that this did not rectify the issue and the users are still experiencing intermittent connection dropping to their file shares over the VPN!

I have a request to establish a site to site VPN with a customer. While collecting the information I give them our local network subnet which is a private subnet (192.168.5.0). They asked me if I could give them a public address instead. They can not work with the 192.168.5 subnet. Is this possible?
My side of the VPN is an ASA 5505 running 8.2(2). The other side i believe is a Checkpoint.
