Server load balancing onto itself

[arthurlove]

hi

I have a customer with 4710 that load balances inbound traffic onto 2 servers. this works

There is also a requirement for the servers that are load balnced to [what seems to me ] to load balance onto themselves and for other server on the same vlan to use the servers in the farm in a load balanced way.

driving me bonkers ......

any ideas ?

thanks

this is possible with client nat.

By nating the source ip , you trick the server to believe the connection comes from another device.

So, all you need is a policy to dynamically nat request coming in.

You add this new policy on the server side interface so that only requests coming from the servers are source nated.

This sounds like a tricky routing and load-balancing scenario. I’d check the ACE 4710’s behavior for connections originating from the server farm itself, particularly source NAT and return-path handling. Hairpinning may be required for the servers to reach the VIP and still be load balanced correctly.
