Dual Wan's CentOS "Adding More IPS"
I've been searching everywhere on the web for this.
I have dual nic's, I want to assign multiple static ips on each network
I already have it configured so that ISP 1
is eth0, eth0:0, and eth0:1 the network config is a block of statics
and I am using say 75.160.x.x, 75.160.x.y and 75.160.x.z it has a subnet mask of 255.255.255.248
isp 2 I have configured this nic as eth1, eth1:0 and eth1:1, I have also enabled tcp ip v4 ip forwarding in my sysctl file. and its subnetmask is 255.255.255.240
ips are 75.161.x.x, 75.161.x.y and 75.161.x.z
Also both networks have separate gateways and should use the separate gateways.
However whenever I enable eth1 both nic's no longer work eth0 dies and cannot be pinged from the internet. neither can eth1
So the question is how can I get both nic’s working and allowing both ips to function with the isps.
I am trying to move my mail accounts and a few virtual website to the new isp so I need each nic and ips to work there respected isps
also each network has its own router and gateway.
