Subject: [FW-1] Check Point Firewall-1 Log analysis


Hi all,


Currently I am working on a project that requires me to look into details
of the log generated from FW-1, is there any useful document or guideline
which could explain most of the error/block/reject messages displayed
in the last column of the log view?


Thanks,
Geoffrey
