evaluating Automap port usage

Since the floating point IP is typically same, the max. concurrent connections on the system or on the specific VIP or virtual will give you how much SNAT usage is potential.

For e.g. if all your virtuals use automap and the system is doing 60K concurrent connections, then quite likely you could run into SNAT port exhaustion.

I typically setup each virtual with a 1 IP SNAT pool and set the SNAT port setting to "preserve". This provides a quick way to chain the server side connection using the src port to the client side connection(ofcourse assuming src port was preserved ;-) but with 1 SNAT pool IP, this seems more often the case than not !!)

Best.
