I have a client whos recently purchased a Cisco 2811 to place in front of their ASA firewall to act as a perimeter router. Their Firewall terminates their VPN connection and now since the perimeter router is in place the firewalls Outside interface is no longer internet facing. How do I NAT through an IPSEC VPN connection to the firewall? They dont want to move the VPN termination to the 2811. Also to make matters worse they only have one statically assigned IP.
Ive done this before but simply NATd a whole IP address through since that client had plenty to spare&
