You can't use 2 default route. It's a non-sense, "default route" mean "send it there when you don't know where else to send". You can (and should) only have ONE default route.
However, if you want to do some "special" routing, like to send all trafic related to a certain service to a certain gateway, you could use iptables to force routing. This is probably what you need. You could also use some routing daemon (routed, gated, etc...) and routing protocol (RIP, OSPF, PIM, ...). I never worked with all this, but if I remember my network courses rigt, you could use this to setup some "different cost" path on your system. I have no clue how useful this would be for you. And keep in mind all what I said about it is quite outdated. |
very very thanks, it was everything that I needed to know...
now... go to iproute2... |
