Hello, I'm entirely new to the whole Captive Portal procedure, but I'm learning about it because I need to control guest access to my newly very fast broadband (4G). As part of that process I thought I'd start by setting up a Freeradius server. I run our B&B web site (and several others, for clients) on a cloud server (the OS is Centos 7). Naturally this runs an Apache server, and MySQL. I assumed that the Freeradius server would run alongside these. Is that correct? I set it up via SSH following the 'hard way' described at: https://draculaservers.com/tutorials/freeradius-centos-7-mysql/ Everything appeared to go perfectly, to the point where it appeared I could run the Freeradius server in debug mode. Then I spotted that I could no longer log in to my WHM/cPanel, nor could I access several of the hosted web sites. I couldn't allow that situation to continue. So I disabled the Freeradius server and the 'firewalld' services. After rebooting the cloud server things cam back to normal. I'm not sure, but I suspect the problem may have been in the 'firewalld' settings. Would these have over-ridden the normal server firewall policy? If so, what should I do about it? I could add the 1812 and 1813 ports to the existing firewall policy, but would that work? I'd be grateful for some help here, please.
