[gentoo-user] [OT] Redirecting traffic for a TCP port to another gateway

[Dan Johansson]

Slight Off-topic, but at least the host are Gentoo.

Is it possible, using iptables or something equivalent, to redirect 
traffic to some specific TCP ports to another gateway than the 
default-gateway?

Eg.

Host 192.168.1.100/24 has a default-gateway of 192.168.1.1
Now I want to send all traffic from this host to destination-tcp-port 80 
to gateway 192.168.2.1 instead (the host has a second interface with the 
address 192.168.2.100/24 as well).
I only want the traffic to port 80 to go thru this GW (and then to its 
final destination).
And port 80 is just an example, it could be port 12345 as well.

Is this possible? If yes, any suggestion on how to do it?
