Cisco VPN Client + WRVS4400N

Jul 17, 2007 1 Replies

I have a new LinkSys / Cisco WRVS4400N that for the most part is working flawlessly... BUT I can not establish a VPN tunnel. The client work perfectly everywhere else...



These are the logs from the client when behind the WRVS

Some routers and network devices do not permit the bi-directional communication as nicely as others. A true Cisco router does permit this with basic NAT configuration. Just because Cisco bought Linksys does not mean that the Linksys products are now as good as the actual Cisco devices.

Attempt to connect using your Cisco VPN client with the profile using TCP and then with UDP. See if the results are different either way. We do not know what your VPN server is configured to allow for its connections - TCP or UDP or both. Your Cisco VPN client will be probably be transmitting in the UDP configuration to destination UDP port 500 and 62515.
