I have a PIX 515 with version 6.3(3). I have a site to site VPN up and running fine. I am adding client VPN access to this now. All clients will use the Cisco VPN Client 4.6. I followed some instructions I found online and have made the connection to the PIX from a client.

The problem is that when I ping from the client to inisde (192.168.0.75) I get no response. I have done a tcpdump on the inside host and see the echo-request arriving and the echo-response leaving. When I do a debug icmp trace on the PIX I I see the request and reply, but I can't see where the reply is going. I an sure it is not going out the correct tunnel. It may be going out the site to site tunnel but I can't figure out how to see which tunnel that reply is going out on.
Is there any debugging techniques that I can use to verify this?
