i like to place a firewall device behind my Cisco 800 series (836 IOS 12.4). I like to forward all ports and protocols to this firewall. In the Cisco are commands like these: "ip nat inside source static tcp 10.0.0.201 25 interface Dialer1 25".
Is it possible to use a command simmular to the one above to forward all ports and protocols from Dialer1 to 10.0.0.201 ??
