gif tunnel problem.
Hi, This is the first time I've looked at gif tunnels and I'm only trying to do something simple (by that I mean no IPsec, etc.) Diagrams are always useful for this, so here goes: (int) (ext) (ext) (int) xl0 192.168.0.1 xl1 a.b.c.d - 'net - sis0 w.x.y.z rl0 192.168.1.1 192.168.0.x/24 192.168.1.x/24 That's a pretty poor diagram, sorry. Basically HostA has is the default router for 192.168.0.0/24 with in 192.168.0.1 and external ip a.b.c.d. HostB is the same for 192.168.1.0/24 with external ip w.x.y.z. I want to set up an unencrypted tunnel between the two subnets using gif. So far on HostA I have: ifconfig gif0 create ifconfig gif0 tunnel a.b.c.d w.x.y.z ifconfig gif0 192.168.0.1 192.168.1.1 and on HostB: ifconfig gif0 create ifconfig gif0 tunnel w.x.y.z a.b.c.d ifconfig gif0 192.168.1.1 192.168.0.1 I got these from the IPsec chapter in the handbook. It states at this point I should be able to ping 192.168.1.1 from HostA. This does not work. I see the echo in gif0 (using tcpdump) but it never seems to exit the gif tunnel and hit xl1. The same is true for HostB. netstat -rn on HostA shows: 192.168.1.1192.168.0.1UH 0 3183 gif0 with an equivalent entry on HostB. What am I doing wrong? I've tried to follow the chapter as best I can but it has been little help. Anybody able to point out the error in my ways?
