Hello, I have some questions about installing a SSL Cert on my ISPConfig 3 (master/master) Multi-server setup. I'm running: two OpenVZ containers on Debian 7 x64 with ISPConfig 22.214.171.124p8 in a Master/Master cluster. srv1.mycompany.com 126.96.36.199 srv2.mycompany.com 188.8.131.52 To let my customers access to the ISPConfig interface, I'm doing Round-robin with two "A" records like: https://cp.mycompany.com:8080 --> 184.108.40.206 https://cp.mycompany.com:8080 --> 220.127.116.11 and also I have a reseller who's doing the same thing with his own domain name, like: https://cp.reseller.com:8080 --> 18.104.22.168 https://cp.reseller.com:8080 --> 22.214.171.124 My goal is to avoid the warnings about the self signed certificates when accessing to the ISPConfig interface. For this I want to buy a SSL Cert, but I don't know what kind of SSL Cert is the best advised for my setup: separate SSL Certs for each server or a Wildcard certificate? considering that my reseller want to profit of this feature too. Another question: there are posibility to do this with a free SSL solution like https://letsencrypt.org/ ? Thanks in advance for your reply, Regards !
