Your concept is right, I think your syntax is wrong. I use this sytnax: # ifconfig gif0 create # gifconfig gif0 tunnel x.y.z.1 x.y.z.2 # ifconfig gif0 10.255.255.1 10.255.255.2 netmask 255.255.255.252 # route add -net 10.2.0.0/24 10.255.255.2 Pay close attention to the "tunnel" keyword on line 2 above. Also, make sure gateway_enable="YES" is in /etc/rc.conf. Nick Rogness <nick@rogness.net> - How many people here have telekenetic powers?
