Hello dear all, I run FreeBSD-4.0 (no changes on the generic kernel) and try to establish a tunnel between a Linux pc and the FreeBSD pc. Unfortunately there is no documentation in the book how should it work, not even for tunnel from FreeBSD to FreeBSD. I have found Information in Internet and I use of course the commands # gifconfig gif0 inet IPv4(1) IPv4(2) (tunnel endpoints) # ifconfig gif0 up # route add -inet6 3ffe:bla:bla::bla -prefixlen 64 -interface gif0 On the other side for Linux I have togive # ifconfig sit0 up # ifconfig sit0 tunnel ::IPV4(remote) # route -A inet6 add 3ffe:..etc. fe80::IPV4(remote) dev sit1 (sit1 will be automatically there when one configures sit0) This address: fe80::IPv4(remote) appears as nexthop in the routing table of the Linux pc, as well as the fe80::IPv4(local). These are addresses on Link which i don't automatically get on the FreeBSD pc! And of course I can't reach the FreeBSD and inversely if they don't understand the same on Link addresse. I hapenned to see on the routing table of a FreeBSD pc, (a side on the internet) that the fe80::IPv4 address was included. Can anybody give me a hint? It will be greatly appreciated.
