I have a network with one public IP address assigned to a watchgaurd firebox x500 firewall. I need to install a cisco 3000 concentrator behind this firewall. The lan port on the cisco already has an internal address 192.168.0.249 ... what ip do i assign the public port? The firebox is providing NAT so, I am not sure if I can give the cisco public ip a private (192.168.0.248) address.
Also, how do i tell the firebox that all vpn traffic should be forwarded to the this cisco...
