Re: How to Setup Networking when connected to 2 networks

ok, so it says "don't do that" but what's the solution?

Like I said, if I removed the 0.0.0.0 route entry for the 10.x.x.x network
its all works fine UNTIL something magical happens and decides to
automagically add back that deleted route.

What's doing that?
