Need help in configuring NAT on this Friday Afternoon...

Answered Question
Sep 5th, 2008

ok, my brain is no longuer functioning right...

Need to nat an external IP to an internal IP (or port forward of somekind).


External IP on E1/1 port 25


Internal IP on F0/1 port 25

How could I do this?

This is on a 3600 router, I know it's not a firewall but can this still be done? if so, How?

I have this problem too.

You must also enable NAT to happen on the interfaces that it passes through as well.

like; ip nat inside (allow inbound NAT)

Here is an example..

ip nat inside source static tcp 80 interface serial0 80

Hope that helps.

so this would work for inbound traffic comming from the outside being routed to the internal device?
