No luck on freebsd-net, so trying -questions


I'm having a problem with Multi destination gif tunnel.  Here the useful
setup info.

////////////////////////////////////////////////////////////////////
// Tunnel setup:

hadji# gifconfig -a
gif0: flags=9011<UP,POINTOPOINT,LINK0,MULTICAST> mtu 1280
        inet 192.168.254.9 --> 192.168.254.10 netmask 0xffffff00 
        inet 192.168.254.1 --> 192.168.254.2 netmask 0xffffff00 
        physical address inet 24.28.70.222 --> 0.0.0.0


hadji# netstat -rn
.
192.168.254.2      24.27.51.59        UHS         2       13     gif0
192.168.254.10     3.9.7.22           UH          0        0     gif0
.

////////////////////////////////////////////////////////////////////
// OK I can ping the other side of the tunnel

hadji# ping 192.168.254.2
PING 192.168.254.2 (192.168.254.2): 56 data bytes
64 bytes from 192.168.254.2: icmp_seq=0 ttl=255 time=89.068 ms

////////////////////////////////////////////////////////////////////


OK, so all looks well.  Now we need to add a route to the far network

hadji# route add -net 192.168.10.0 192.168.254.2


////////////////////////////////////////////////////////////////////
////OK, now lets try to reach it:

hadji# ping 192.168.10.16
PING 192.168.10.16 (192.168.10.16): 56 data bytes
ping: sendto: Input/output error
ping: sendto: Input/output error

////////////////////////////////////////////////////////////////////


Input/output error...?  Someone have some ideas?
