port forwarding on 2600 router

port forwarding on 2600 router

(OP)
Hi,

does anyone know what would cause a port forward not to work from a nat'd ip. I am simply putting a statement such as

"ip nat inside source static tcp <internal ip> 1234 <external public nat'd ip> 1234 extendable"

When i do a show ip nat translation I see the port being forwarded as a different port to the internal ip address.

any help is much appreciated. Thanks.

RE: port forwarding on 2600 router

can you please post your results here so we can see..

and also config :D

technically it shouldn't be happening..
also you dont need the extendable command there unless you are creating multiple nats to the same global/or local address..

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.
