Route only some traffic trough VPN

Is it possible to route only certain traffic through VPN and other through default gw route?

I have tried to google it, i didn't find anything usefull.

Thank you

If the traffic is all to a certain network you could add a routing entry specifying where to route it through:
route add -net 192.57.66.0 netmask 255.255.255.0 gw 1.2.3.4

Check 'man route' for more examples.

Yes, that will route all traffic through that gw. But, what I want is to redirect traffic from certain ports through other gw.

Replace 'eth1' with 'ppp0' or 'tun0' or whatever your VPN interface is:

Then for the ports you want to send via the VPN, add a rule like this:

iptables -t mangle -A OUTPUT -p tcp --dport XX -m state --state NEW -j MARK --set-mark 102
