I must route all traffic from first server to second server and next to third server.
Like this: server1 -> server2 -> server3
I use Debian Wheezy. Can anyone tell how to do this with iproute?

If you want to route all trafic from a machine to another you can use iptables to match on a port:
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p tcp --dport 1111 -j DNAT --to-destination 2.2.2.2:1111
iptables -t nat -A POSTROUTING -j MASQUERADE

Ok, thanks. Could you tell how to route all trafic from all ports? – MarcinM Jun 17 '14 at 10:28

Maybe with this : iptables -t nat -A PREROUTING -d 1.1.1.1 -j DNAT --to-destination 2.2.2.2 ? – Thomas L. Jun 17 '14 at 11:52
