tega ne razumem: imaš pač routing tabelo, ki (običajno) podaja kup
pravil v slogu: paket za to in to omrežje (IP + maska) pošlji na
tale vmesnik (in morda proti temu GW).

rabiš (predpostavljava jedro 2.4.x) netfilter, NAT, in pravilo v
POSTROUTING verigi; slednje bi šlo nekako takole:
iptables -t nat -A POSTROUTING -d <ORIG_DEST_IP> -j DNAT \
--to-destination <NEW_DEST_IP>
več o IP paketnem filtru in najdeš na: http://www.netfilter.org/;
to bo brez dvoma koristno branje za vas na Iskratelu!
