There are more than 10 clients, so that really isn't an option. i (personally) would go the keep-it-simple route; and just SNAT all port 5190 traffic to the same IP and move on with my life; i.e: iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -j SNAT --to 5.5.5.69 iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 5.5.5.60-5.5.5.69 if you're just dying to go "hog wild" with netfilter extensions--there's probably some crazy combination of random/recent/marking that could be used to split your tcp 5190 traffic into 10 "sticky" pools, each with their own SNAT... if that gives you a headache--you could also split up your /22 semi-evenly over the 10 public IP's manually, like: iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.60.0/25 -j SNAT --to 5.5.5.60 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.60.128/25 -j SNAT --to 5.5.5.61 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.61.0/25 -j SNAT --to 5.5.5.62 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.61.128/25 -j SNAT --to 5.5.5.63 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.62.0/25 -j SNAT --to 5.5.5.64 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.62.128/25 -j SNAT --to 5.5.5.65 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.63.0/25 -j SNAT --to 5.5.5.66 iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 5190 \ -s 10.176.63.128/25 -j SNAT --to 5.5.5.67 iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 5.5.5.60-5.5.5.69 -j -- Jason Opperisano <opie@xxxxxxxxxxx>
