hopefully someone can help here is the deal, we have 3 servers, 2 main servers and one mirror/ backup server. out T3 is provided with a cisco router running both LAN and WAn through one interface. here is the problem. in order for the cisco router to route internal traffic to our servers which have exnternal IPs, i must add an internal address to the eth0 interfaces. lets use this as an example. our outside address is 188.8.131.52 and the internal ip is 192.168.1.10 both of these are on eth0. If i remove the 192 addess no LAN pc can get to the server even from the 184.108.40.206 Wan address. this is where the problem happens. our servers all have a gigabit eth1 card that need to be on 192.168.1.11 also. when i transferr data from 192.168.1.11, instead of going through eth1 it all transferrers through eth0. is there a way to limit the ip traffic to their respective interfaces? as in i only want 192.168.1.11 to go through eth1.
