--zhXaljGHf11kAtnf Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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: 192.168.1.1 192.168.0.1 UH 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? Thanks a lot, -lewiz. --=20 I was so much older then, I'm younger than that now. --Bob Dylan, 1964. ------------------------------------------------------------------------ -| msn:purple@lewiz.net | jabber:lewiz@jabber.org | url:www.lewiz.org |- --zhXaljGHf11kAtnf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAWJ8hItq0KFQv7T8RAuQzAKCOzAj6SliRi/R4w4XpZmWfyCBl9gCghiDh M7/DPGQlPGkvs8mIanLV7l0= =o2/I -----END PGP SIGNATURE----- --zhXaljGHf11kAtnf--
