I am sitting with a problem where I have a virtual server x.x.82.16 connected to a cisco router. I have 5 physical servers hanging off the virtual server. Basically the virtual server (.16) acts as a load balancer by assigning a connection to the first server it finds available.
What is happening is we need to add the mac and ip into the arp table to get connectivity to the .16 server. That works for roughly 10 minutes then we cannot get to any of the servers (x.x.82.11 to .16) Once we remove the ARP entry and re-add it things work again.
Is there something one can do to resolve this issue by making the arp entry permanent?
