Re: [LARTC] how to force iproute2 to FORWARD to another interface

[David.Lamparter@t-online.de (David Lamparter)]

You may want to try the (unoffical) 'ROUTE' netfilter patch (see 
patch-o-matic at www.netfilter.org)

after applying and re-compiling kernel + iptables use:
iptables -t mangle -A PREROUTING -i nsc5 -d 212.31.242.98 -j ROUTE 
--iface ppp0

(maybe there is another possibility without recompiling kernel ... but I 
didn't find anything...)
