Hairpinning on the ACE

jason.williams — Tue, 10 Apr 2012 21:12:51 GMT

We have a server that is in a serverfarm behind an ACE. We're trying to test something, and I essentially need the server to connect to itself over the VIP.

However, I cannot ping or connect to the VIP from this server.

I do have source NAT enabled, and it seems to be working. But that being the case, it's the VIP trying to connect to the VIP.

Did any of that make sense?

Any help would be appreciated.

Thanks.

Jason

Hello Jason,

What you are looking sound like server initiation where the traffic is started by the servers which hit the VIP to load balance the traffic to a specific serverfarm(in this case the same one where it resides in your scenario)

This link might give an idea of what you might require:

Hope this helps!!!
