I added 2 nameservers to a 3.1 multiserver installation, and those servers already had ufw configured in them prior to installing ispconfig, with the simple rules below. I chose `Configure Firewall Server: y` during install, and the Server Config is set to ufw fireall, but any changes to firewall records for these servers do not propogate to the live firewall rules. Any pointers on how to get ispconfig's ufw rules to take over the locally configured rules? I did run server.sh in debug mode and it shows changes propogate to the database (port 1234 is test): Code: [email protected]:/etc/bind# /usr/local/ispconfig/server/server.sh 09.08.2016-09:41 - DEBUG - Found 1 changes, starting update process. 09.08.2016-09:41 - DEBUG - Replicated from master: REPLACE INTO `firewall` (`firewall_id`,`sys_userid`,`sys_groupid`,`sys_perm_user`,`sys_perm_group`,`sys_perm_other`,`server_id`,`tcp_port`,`udp_port`,`active`) VALUES ('11','1','1','riud','riud','','8','22,53,1234','53','y') 09.08.2016-09:41 - DEBUG - Processed datalog_id 2624 09.08.2016-09:41 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_lock finished. But they don't show ip in iptables or ufw status: Code: # ufw status Status: active To Action From -- ------ ---- 22 ALLOW Anywhere DNS ALLOW Anywhere 22 ALLOW Anywhere (v6) DNS (v6) ALLOW Anywhere (v6) Code: # iptables -L -n -v | grep 1234 # I don't know if having used the 'DNS' app name, rather than just port 53, throws it off?
