and RSTP) create two sessions per connection.

To monitor session limiting, return to this screen periodically and check the display of Total
Number of Packets Dropped due to Session Limit, which indicates that session limits have been
reached.

(VoIP) sessions that use the Session Initiation Protocol (SIP) across the firewall and provides
support for multiple SIP clients. ALG support for SIP is disabled by default.
