Re: NAT Port Forwarding Cammand

You need "ip nat inside" under the interface on which you will reach and "ip nat outside" under the WAN interface with the

global config command is like this to do static port mapping

ip nat inside source static tcp 5631 5631 extendable

ip nat inside source static udp 5632 5632 extendable

For more information pl. visit

where static port mapping form outside to inside tcp port 80 is explained for the internal web server..Thx..Tejal

Re: NAT Port Forwarding Cammand

Thanks so much!! I will try it. Is there a generic way to test by pinging say

Also, is there a way to list static routes that I have setup on the router? I need to be able to disable these ports also.... what is the best way to take out the PAT statements? THANKS!
