Hi there Tomas!
: iptables -t nat -I PREROUTING 4 -i eth0 -d x -p tcp --dport 80 \
: -j DNAT --to y when/how do i specify port 7865?
This should do the trick:
iptables -t nat -I PREROUTING 4 -i eth0 -d $PUB_IP -p tcp --dport 80 \
-j DNAT --to-destination $PRIV_IP:7865
Check out Oskar Andreeason''s tutorial on this very matter.

Ciao for now,
