Route-map on a NAT with dialer interface

Hello all,

 

On a Cisco 800 series router why can't I type this command?

"ip nat inside source static tcp 192.168.1.5 443 interface dialer1 443 route-map NONAT"

 

I have to type this command for it to work:

ip nat inside source static tcp 192.168.1.5 443 X.X.X.X 443 oute-map NONAT

(Where X.X.X.X = IP address of dialer1)

 

Seems to work ok. Just can't understand why I can't use the top one.

 

Thanks

I have not run into this before - and I am certainly not authoritative on this. But what makes sense to me is that when you are doing a static NAT/port forwarding then the IOS needs to translate an IP address to an IP address. I know it works ok to specify the interface when you are doing dynamic translations. But I wonder if the logic to process is different when doing static translation/port forwarding.

 

I also wonder if it might have anything to do with the fact that you are using a route map to control the translation?
