Hi,

the flag for ip-forwarding is certainly active as the firewall serves for
other tasks that run well.

Does this certainly is not : "... and which destination network is not the
cipes' network ..." ?

Now for the ipchains that's perhaps another thing ... I have added following
to my rc.firewall :

   /sbin/ipchains -A input  -i $CIPE_INTERFACE -s $LOCALNET_1 -j ACCEPT -l
   /sbin/ipchains -A output -i $CIPE_INTERFACE -d $LOCALNET_1 -j ACCEPT -l

   /sbin/ipchains -A forward -i $CIPE_INTERFACE -d $LOCALNET_1 -j ACCEPT -l

Would this do the trick ? Apparently not, because it doesn't ... and
ipchains are not my strongest side ...
More I fail to see why ipchains has something to do for such a simple
routing task ...

Best greetings !
