what does ACE do with a packet?

axfalk · ‎05-17-2010

I understand once ACE determines which back-end load balanced server is getting tha packet based on the load balance algorithm, it then performs an implicit destination NAT that changes the dest address of the packet to that of the back-end server's. Does it also replace the client address with the VIP address?

Thanks..

Hi,

By default, the original src.address is retained, when ACE forwards the packet to selected rserver.

You have the option of configuring client-nat on incoming client-requests, by which you're replacering the original src.ip with an ip, usually picked from the address-range of the outgoing ACE-interface. This can be done as either dynamic (PAT) or static NAT.
