I followed Till's guide https://www.howtoforge.com/installi...tabase-cluster-on-debian-6.0-with-ispconfig-3 to setup a high availability mirrored Centos 7 master and slave ISPConfig 3 with appropriate modifications for centos 7. I cannot access ISPConfig interface on the Slave server, whereas it is working fine on the master server. Running nmap to the slave server, revealed that all ports are closed except ssh, I'm not sure why. I believe I should be able to access both master & slave ISPConfig interfaces. Firewalld is disabled on both servers. Both servers are on the same private subnets. Thanks
ISPConfig does not close any ports in this setup, so there must be a firewall runing or the services have not been started.
