Active IP Block in Smoothwall Express decided would block...

The firewall reacted to incoming traffic from plesk on port 21.... (was using filezilla.. had been since day 1) why should happen now? specified passive in filezilla now, but don't see why should suddenly block.. has ftp on plesk changed ?
