Hi,
I have a linux router in my lan with two nic's to two isp's and i also have two nic's for the lan. I have on eth0 the ip from ISP1 on eth2 the ip from ISP2 on eth1 i have 192.168.1.1 and on eth3 i have 192.168.1.2. What i'am trying to is when i give 192.168.1.1 as gateway on a client in my lan then the traffic go's over ISP1 and when i give as gateway 192.168.1.2 that the traffic go's over ISP2. How can i manage this?
