We have a PIX 501 running 6.2 and are having problems with some clients connecting via VPN that are behind wireless routers. They are able to connect but cannot ping anything on the internal network. From doing some research - it seems like the solution is the nat-traversal but unfortunately that command is only available in 6.3 and later.
Is there anything else I can do to get this working or is it time to buy a new firewall? Any help appreciated!
Cheers, John
