Thanks for this link. It;s very useful for VPN .
I want to prepare for the exam JNCIS FWV exam. Can you please guide me.
I have good experience with Juniper FW's and also with NSM.
If you can help me with any reading document then it will be very helpful as I can not afford to take the training.

See this previous thread for study material on the ScreenOS firewall certifications.

Just to add on: Make sure to Turn ON the dbuf buffer.
This sets up a portion of memory required to hold the debug information needed. When troubleshooting the firewall, the output of the debug will be directed either to the console or to a buffer. Usually, the debugging information should go to the buffer, opposed to the console. When information is sent to the console, it is resource intensive, and can produce performance problems if too much debugging information is sent to the console. The alternative is sending the data to a buffer called dbuf.
From the command line interface (CLI): set console dbuf
I recently faced a problem, where someone is deubgging the packets to the self and due the large dbuf stream entry, it slowed the firewall and caused issues.
