1. Although the maximum IPSec and WebVPN sessions add up to more than the maximum VPN sessions, the combined sessions should not exceed the VPN
session limit. If you exceed the maximum VPN sessions, you can overload the security appliance, so be sure to size your network appropriately.
2. The concurrent firewall connections are based on a traffic mix of 80% TCP and 20% UDP, with 1 host and 1 dynamic translation for every 4 connections.
