Strange Connectivity Problem

I have a strange problem that I don't really understand.

I have a site-to-site VPN configured between two ASA5520's. All is OK except for one Windows 2003 server which occasionally I loose connectivity to for no apparent reason. Checking the other end of the VPN reveales that the servers looses connectivity with my PC too as if the tunnel has dropped. A ping times out after a couple of hops, and the SA shows packets leaving site (encrypted) but nothing comming back. The same is for the other side of the VPN. The tunnel has not dropped because the connected timer has not restarted.

To resolve the situation I have to run a TRACERT to the server from my PC & then I can ping the server once more !! The a couple of days later it will go again.

Any ideas ? What's different about a TRACERT from a PING ??

Regards,

Stuart

Re: Strange Connectivity Problem

Tracert- Traceroute gives information routing path(how many router it crossed).

Check your NAT configuration for VPN connectivity problem.
