Cisco VPN Client disconnecting. Reason 412...

[REM2500]

Hi all. I have a problem with connecting to a VPN. Here is the situation.

At our office, when I try to connect to the VPN at a remote location, I get the following error usually around 15 minutes after it has been connected (sometimes longer sometimes shorter):

Secure VPN Connection terminated locally by the Client.
Reason 412: The remote peer is no longer responding.

We recently switched ISP and I had once thought it was an ISP issue. We were with AT&T DSL and got the issue. However I can take my laptop home (the same PC I use at work) and connect and never get the error. So the new ISP is the same ISP I have at home. Therefor, I had considered it some issue with the ISP because people at other locations can connect to the VPN with no problem.

Well now we have the same ISP at the office that we have at home and I am getting same issue. Anyone have any ideas on how I can fix this?

Thanks,

We always get the same error message and we are connecting to a site that never changes and has a staic IP.

I think I have found the issue and will be testing this today. On my home router which is a Linksys wrt54g with DD-WRT firmware installed, there is a check box to enable IPSec passthrough which was enabled when I was connecting from home. I think that equivilant on the router here at the office is not enabled and so I will check that out, do some testing and report back.

Thanks for the reply!

So I am still having the issue. I found out that, by default, the firewall at work allows IPSEC traffic. Also, I have opened every port, and then some, that the documentaion for the Cisco VPN client requests and I am still getting this issue...

Any other ideas?

Thanks,

I fixed this (for the time being) by having the user who was using the VPN, to connect using the client and then opening a command prompt and continually pinging a server on the remote network. This seems to keep the connection alive.
