Auto run config specified command on firewall open/close
It would be really cool if you could add three config entries e.g.
autorun_while_open = <string>
autorun_on_open = <string>
autorun_on_close = <string>
Each of the strings specify a shell command which is run on the appropriate event. autorun_while_open would spawn the child process and kill it when the firewall is closed.
This way, on firewall open, I could start an SSH tunnel for SMTP so I can still use SUN's mailserver from outside, and when I close the firewall, the tunnel is closed to.
