Ok i found why the "custom" rules disappared. after adding a new rule like
ufw insert 1 deny from some_ip_adres to any app OpenSSH The GEOIP rule is gone. For now i've created a cron script which checked for my rule and reloads it.. I consider the disaperance of the rule because of the adding also a bug. This is the first firewall software where i notice behaivior like this. Greetz, Louis
