I have 2 internet providers (each one having a different gateway). Behind the router there are around 100 clients that are SNAT-ed. I want some clients to be SNAT-ed to the first provider, while the others to the second one. The following lines should work: iptables -t nat -A POSTROUTING -s 172.17.31.81 -j SNAT --to-source $INET_IP_1 iptables -t nat -A POSTROUTING -s 172.17.31.82 -j SNAT --to-source $INET_IP_2 But... there is a problem... I have to make the packet (after it has been SNAT-ed) follow the gateway corresponding to the $INET_IP_1 or to the $INET_IP_2 respectively. In my routing table I have only one default route... corresponding to one of the gateways. Is it possible to have 2 default routes? Is there a more elegant way to solve this problem? Is there a way to tell the routing table that every request that has the source address $INET_IP_1 follow the $GW_1, and every request that has the source address $INET_IP_2 follow the $GW_2?
