I have a 1811 connected to the internet with a cable modem and a dynamic IP. I'm looking to forward port 80 from the outside IP to an internal host for testing. I've used the SDM to setup the router but I haven't found a way to forward the port that I need done. I'm not necessarily set on using the SDM to do this, I just don't want to set it up so if I make a change that gets over written later by the SDM.
If anyone could that would be greatly appreciated.
ip nat inside source static tcp 192.168.1.1 80 interface serial 0 80
Or are you looking to combine this with a service like Dynamic DNS (and want to access the service remotely using the hostname)?
