ACE 4710 - Server Gateway

tobin_jim — Thu, 26 May 2011 09:39:48 GMT

I'm setting up an ACE 4710 in our test lab before deploying in production. Do the test web servers I am using need to use the ACE as their default gateway? The are currently configured to use a multilayer switch on their vlan as their gateway but I'm guessing the ACE needs to see the return traffic for load balancing to work correctly?

Hi Jim,

you are correct. In most of the situations the ACE must see the return traffic and it is preferable because the client needs to get the reply from the ACE VIP.

You can accomplish that by modifing the routing table of the servers if the clients contacting the ACE VIPs all come from some subnets or you can do source NAT on the ACE and hence the servers will see the requests as coming from the LAN and won't use the default gateway at all.
