You should be able to do this by marking packets and routing with ip route. Something like this: iptables -A OUTPUT -t mangle -p tcp --sport 22 -j MARK --set-mark 1 ip rule add fwmark 1 table table1 ip route add table table1 default dev eth1 I'm not sure, but you might need to SNAT as well: iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to-source a.b.Y.21 Of course, that will route any SSH connection as such, not just SFTP.
