Can somebody explain to me how to configure this. If you have an ASA for your firewall and a user on your internal network has a VPN client where they connect to a remote server on the internet how to you allow IPSEC pass-through so the internal user can establish a connection? Our internal network is of course being nat'd by the ASA.
The Cisco VPN Client uses the public IP address in order to establish the IPsec VPN with the VPN server. Along with the static NAT command, configure the access list in order to allow the VPN traffic on the PIX Firewall. Following link may help you
