Scenario: using vtun to build a Lan-to-Lan VPN. One end FreeBSD, one end Linux.
On the BSD box I can set up a route directly through the tun0 device without having to assign it an IP address, like this: ifconfig tun0 up mtu 1450 -arp route add 192.168.10.0/24 -interface tun0 and it works just fine. On Linux (I've tried Gentoo and Redhat) it would seem that the following should work: ifconfig tun0 up mtu 1450 pointopoint route add -net 192.168.10.0/24 dev tun0 However I get a: SIOCADDRT: No such device which suggests that the tun device doesn't support the right ioctl variants. Has anyone done this? It's easy enough to do it using throw-away IP addresses for the two "ends" of the tunnel, but it's neater if they can be avoided. -- gentoo-user@gentoo.org mailing list
