cisco 877 config


Thank you for taking a look at my question.  

Just a quick one.  I need to allow through the router a UDP port range of 4000-4100

I know how to do it for single ports, is it even possible to do a port range?

Something along the lines of:

access-list 101 permit tcp range 4000 4100

It depends if you want to do this routed or via NAT.

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.

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

would it be like this?

access-list 101 permit tcp 192.168.x.x 203.x.x.x range 4000 4100
