I think iptables can provide this type of redirecting

Hello zovres,

You can do port forwarding using the NAT function in iptables. For this you need the 'iptables_nat' and 'ip_conntrack' modules loaded.

# iptables -t nat -A PREROUTING -d 'IP of eth0' -p tcp --dport 22 -j DNAT --to 'IP of eth1'.

After issuiong this command please restart iptables. I hope this simple redirection would work for you. Please reply if anything comes up.
