Re: [LARTC] routing in tunnel mode

[Nikolay Kichukov <hijacker@oldum.net>]

Hello there, it does not matter what type of network you are trying to 
reach, the Network unreachable error message suggests, that the router 
does not know on which interface(physical) to forward the packets with 
destination -net !

Before the lane you wrote, try this:
route add -net xx.xx.xxx.xxx dev YOURDEVICE

YOURDEVICE will be the device that the network is connected to the 
router via. If it is a sit tunnel, then YOURDEVICE = sit0.

HTH,
