NAT two outside TCP ports to one inside TCP port
Posted by Kevin on November 10th, 2004


Hi,

Do you know how to set up NAT so that two differents TCP port on the outside
interface redirects to the same inside IP/TCP port ?

For example:

ip nat inside source static tcp 192.168.1.1 80 interface Ethernet0 80
and
ip nat inside source static tcp 192.168.1.1 80 interface Ethernet0 8080

Can not cohexist together, setting one will automaticly disable the other
....

Thanks !

I seriously doubt you can do that. What happens if a packet originates
at inside port 80 -- which port should it get mapped to as it goes out?
