pfSense

Hello,

I noticed a weird behaviour with captiveportal when reconfiguring a CP while active users are connected : When administrator saves settings, ipfw rules are automatically flushed.

This is a big problem when editing captive portal settings while some users are connected : user are technically disconnected and are redirected to the login page (because ipfw rules are flushed), but they are still considered as connected and are unable to log-in again (because they are still present in the sqlite database).

This happen because when settings are saved, captiveportal rules are re-appplied unconditionally to the network interface.

One easy/dirty workaround would be to flush sqlite3 database when re-applying ipfw rules (meaning users get will get disconnected, but will be able to login again).

One (maybe better) fix would be to apply ipfw rules only if necessary (eg, when changing the captive portal’s network interface or some key settings) and to connect-back users after applying rules.
