TCP Port Forwarding Range on Cisco 2514.

[andrew4728]

Hey all, this seems like it would be a very easy thing to do, but I cannot figure this one out!

I have read several webpages from Ciscos website concerning NAT translation, and also searched google and yahoo and still cannot find the answer to my question.

I am trying to setup port forwarding for a RANGE of TCP ports.

I know that the following command will forward an individual port (3389) to an inside computer :

ip nat inside source static tcp 192.168.x.x 3389 interface Ethernet0 3389

I am trying to forward TCP 6881-6999 to goto one of my PCs inside my network.

Could anyone help me with this one or point me to a webpage that shows how to forward RANGEs?

Thank you all!

Andrew

You can do a NAT translation at the network (IP) level (not TCP or UDP) and then create an ACL to only allow the specific ports, but I don't think there is a way to do a range with NAT.

ip nat inside source static x.x.x.x y.y.y.y

access-list 100 permit tcp any any range 6881 6999
