Add 2 public subnets on same server.
Posted on 2015-01-09
Our web server has 2 Nics.
A1=Public with GW
B= private with no GW.
Because our public range is out of IPs I need to add a second nic with new subnet A2 =Second public. This one has a different GW.
I cant have 2 GWs so I need static routes. But its not working.
My A and B still work fine but I cant ping A2 from A1 or vice versa.
I did a test from Another server 2 that only has B and A2 and I can ping both A1 and A2 on server 1.
So its definitively a routing GW issue on between A1 and A2 on server 1.
I think the ping comes on A2 but then goes out the default gw on A1 instead of routing back to A2 interface.
I even specified IF in the route to go back to IF 23 which is A2 but its not working.
