Disclaimer: I know this is a *development* list, but I feel the answer
lies deep down in the ipv4 routing code, so it's more likely that I
find help here.
That being said, I have two TUN interfaces that are "cross-connected"

clone of Dave's net-2.6 tree, so it shouldn't be such a
big effort to use git after all. I can also make the patch against
