Hello everybody. I'm running linux 2.6.19 with nth match to alternatively snat outgoing connections to two different ip addresses. Here is: $IPTABLES -t nat -A POSTROUTING -s my_ip --protocol tcp -m multiport --dports 80,443 -m statistic --mode nth --every 2 -j SNAT --to adslA $IPTABLES -t nat -A POSTROUTING -s my_ip --protocol tcp -m multiport --dports 80,443 -j SNAT --to adslB Things are working pretty good, but some applications (home banking for example), don't work correctly. Is there a way to tell iptables to snat always with the same source ip for the same destination host?
