Multi-session PAT - why does multi-session PAT get this name?
Hello firewall experts
I have read configuration guide for ASA 9.1.1 and found the topic of per-session PAT and multi-session PAT.
The configuration explains well about the benefits of using per-session PAT but, it does not talk enough when we should use multi-session PAT and why.
Why did they give the name of multi-session PAT to this multi-session PAT?
What are the application protocols that would be benefitials to use multi-session PAT and why? In the configuration guide, it speak to such protocols as SIP, H.323, and Skinny protocols as the candidates for multi-session PAT but, it does not mention why we should use it or what characteristics of these protocols make multi-session PAT more suitable for them.
