VPN (Problem pinging internal IP from VPN Client

I am running Client 3.6.3 on Windows 2000 pro. It seems to be connected but I can not ping any IP that is behind the PIX. There is only one windows 2000 pro pc in the internet network, and one windows 2000 pro in the outside network. Can anyone help me? I really can not see what is wrong with my configuration....Once client connects to PIX, I received a IP I can see as well. However, I also get an warning "Sev=Warning/3 IKE/0xA3000058 Received malformed message or negotiation no longer active (message id:0xD50CEC90)

Re: VPN (Problem pinging internal IP from VPN Client

CAn't see anything wrong in the config. Does the internal host have a default route pointing to the PIX inside address?

If you double-click on the padlock icon after your tunnel is established, do you see a yellow key next to the network after you try and ping, this indicates that the SA has been successfully built. Do you see the "packets encrypted" counter go up when you ping? Ifyou do a "sho cry ipsec sa" on the PIX, od you see te "Pkts Decaps" counter go up (this indicates the PIX has received those ping packets from your client and has decrypted them)? Do you also see the "Pkts Encaps" counter go up, this indicates the internal host has replied to the pings and sent them to the PIX, and the PIX has encrypted them and sent them back to your PC? Do you also then see the Packets Decrypted counter go up in the client, indicating it has seen the encrypted replies from the PIX?

Checking the 4 counters above and seeing which ones increment and which ones don't should give you a good indication of where the problem lies.

Re: VPN (Problem pinging internal IP from VPN Client

Was this issue resolved? I have a similar issue on Win XP. The Cisco Client V. 3.6.3 passes packets out but receives none. - But it had been working for months.
