Group,
I have a 501 that i want to be a vpn "server". i wish to connecto to it via the cisco vpn client. the client setup is correct as i use it for other cisco vpns. I have done this million times before, but have staired at this for to long. please help
inside is 10.10.11.254 /24
outside is 66.x.x.1 /27
The clinet connects, receives an ip address from the pool (172.16.3.1), and can encrypt packets out.
i even get the networks for the split tunnel.
but when i ping servers in the secured network, i see the packets for encryption heading out. But receive no reply.
debug icmp trace shows me the icmp packets going out and coming back. the source address is the pool address. (172.16.3.1)
pings timeout
i have attached the config
PIX Version 6.3(1)

Is your VPN client machine behind a device that is performing NAT? If so, add the command "isakmp nat-traversal" to your PIX 501's configuration.

Yup, I think too thats a problem of NAT-TRAVERSAL.
Example config:
nat (inside) 0 access-list NONAT
access-list NONAT permit ip Internalnet ISubnet VPN-Pool 255.255.255.0
access-list DYN-VPN-ACL permit ip Internalnet ISubnet VPN-Pool 255.255.255.0
