2.Fixes between 2.01 and 2.02 releases

-The total number of sessions has been limited with 1440. Once the session number reaches 1024, the sessions start getting cleaned aggressively. The aggressive timeout is 60 seconds i.e all sessions older than 60 seconds start getting cleaned. Once the number of sessions drops below 1024 the session cleaning is stopped.

-The session cleaning is handled by a timer thread ("tALCwTimer"). It was running every 500 ms to clean sessions. It is now made to run every 50 ms so that when the sessions are in huge number the timer thread cleans them as quickly as it can.

-The issue with PC Privilege that the DNS traffic from the local out was getting blocked on firewall has been fixed.

-One crash when box is trying to get connected as a PPPoE client has been identified and fixed.

-One crash on user mode when packets which has not been belonging to any of

the

interfaces is entering into DNS loopback, is fixed.
