[nadeembahaduri]

:-[ m a new bie and have basic idea of a firewall. I have PFsense version 1.2.3 and everything is working fine. I have a small issue, In the Services->Proxy Filter->Log ->Blocked i cannot see the logging. It works if i reboot the system, but the next day if i login to again into the GUI i am not able to see the Log.
Any help appreciated. Also how can i keep a backup of this log.
