I really need help. I removed port 3306 ny accident in the ispconfig firewall for every server. I know that ispconfig needs the mysql port for comunicating with servers. On servers without main DB I added the port into the firewall table in dbispconfig, restarted the mysql service and stopped and started the bastille-firewall. But the server.sh script still can't connect to the main DB. What should I do to fix this? I really need help with this!
Remove all firewall rules on the master server with: iptables --flush now the salves should be able to connect to the master again to fetch the firewall rule update that you made in the ispconfig interface. Finally make the same update for the master server to write the rules again on the master.
