I know how to forward one port to a static inside address, i.e. "ip nat inside source static tcp 172.17.1.4 25 interface eth0 25", but I need to forward a port range i.e. 5630-5639. Is there a simpler (better way to do this) other than a separate entry for each port in the range? Oh yeah, it's a Cisco 831 with IOS version 12.4.
I have this problem too.
