Route traffic based on the PORT #

Unanswered Question
May 29th, 2007

Hello all,

I need to setup a rule on a router. Any SMTP traffic destined for a certain I.P address must route traffic to a certain address. The Ip Route command can route traffic based on source and destination I.P addressing, but how can I filter this traffic based on port 25 (smtp)?

Thanks

I have this problem too.

Hi,

You can do PBR (Policy Based Routing), as it is the only mean of source based routing, kindly check the following links and please do come back if you have further questions:
