Ok, so the similar threads didn't really help me on this one, so once again Dear LQ Users, I'm asking for your advice on this matter.
We've got some servers in a datacentre. These are behind a firewall. They are happy. There are no problems.
We now have a load balancer for certain servers. This is requesting that it is the gateway. This is fine for everything that addresses the servers via the load balancers but in the event that the load balancer fails or becomes decommissioned for any particular reason, then we need to be able to automatically route via the firewall.
Is it therefore possible to have something that says
route_eth0="default via 10.x.x.80 alternate via 10.x.x.4"
or similar? I'm guessing that you need to use metrics here to weight the direction the traffic takes. Bear in mind that all these servers have only ONE
ethernet card. Anything else you need to know, please do ask.
Thanks in Advance for any/all assistance rendered.
