Port Forwarding on a Cisco 800 series

Posted on 2010-11-18
Last Modified: 2012-05-10
We have Cisco 800 series router and need to forward a port and a range of ports. It is connected to a SDSL connection to the telco and I was not sure if there was anything special to do with the VLAN in place.

This is what I was going to do. Login to the router and apply the port forward for the single port....

ip nat inside source static udp 5060 interface fe0/0 5060    I believe this is correct?

From this point I need to know how to take care of the range 10000 - 20000. I have looked up where it was suggested to create a IP NAT pool, with an ACL. Is this the best or easiest way?

Also will I need to do anything with the VLAN in place?

I can provide a running config if needed.

jramsier: well I guess I am doing ok on finding sources, as I have the info from iternity too.

My question on the VLAN is, there is already a VLAN setup, so if I add these port forwarding configuration changes, do I need to do anything to the existing VLAN?

jramsier: Do you know how to check to see if the port is forwarded or not?
