It depends if you want to do this routed or via NAT.<br />
<br />
If routed, Don is correct for both inbound and outbound traffic, but if you want to do this inbound via PAT it will not work.

I think I am doing nat for a lot of the other port forwarding.<br />
<br />
say for example the external IP of the router is 203.x.x.x and the internal IP I want those ports to hit is 192.168.x.x.x and the port range is 4000 - 4100<br />
<br />
would it be like this?<br />
<br />
access-list 101 permit tcp 192.168.x.x 0.0.0.255 203.x.x.x 0.0.0.255 range 4000 4100<br />

Hi,<br />
<br />
Thank you for taking a look at my question. &nbsp;<br />
<br />
Just a quick one. &nbsp;I need to allow through the router a UDP port range of 4000-4100<br />
<br />
I know how to do it for single ports, is it even possible to do a port range?<br />

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
