port forwarding on 2600 router

[hortonhearsawho]

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.

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

and also config

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.

The below is what i'm getting:

tcp <correct 1 public nat'd ip>:9620 <correct internal ip>:5678 <correct destination public ip>:32885 <same destination public ip as previous ip in this line>:32885
