Hi, sorry, it tooks me some time to answer, but now I found why if the default route goes inside the tunnel and ipip packets generated by gif are unable to find a way outside the system (other than the default route) it loops on itself. It is probably possible to produce the same effect with a series of misconfigured tunnels. by using two different protocols ip4 in ip6 or ip6 in ip4 you can't get this loop effect. -- Didier Derny didier@omnix.net On Mon, 20 Mar 2000, Mike Tancsa wrote: > At 08:31 AM 3/20/2000 +0000, Didier Derny wrote: > > >it's possible to use gifconfig to build a tunnel between two machine > >but it's not recommended with ipv4 > > Excellent, thanks for the example!
