CentOS - Jul 2018 - Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP?

Good evening from Singapore,


Is there any way I can deploy cPanel web hosting control panel with Microsoft
Exchange 2016 groupware behind one static public IP? Or do I need 2 static
public IP addresses at the minimum? With Exchange 2016 groupware taking up HTTP,
HTTPS, IMAP, IMAPS, POP3, POP3S, SMTP, and SMTP/S ports, I personally don't
think I can deploy cPanel behind the same public IP as Exchange.


Please advise. Perhaps you have a brilliant idea. This is for experimental,
testing and laboratory purposes.


Thank you very much.

You can use bind your cPanel web server to a different port or
(better) you can put your services behind a reverse proxy/load
balancer. In this scenario, for web servers running on the standard
ports (ie TCP 80 and 443), you can use HTTP host headers/SNI to
redirect requests to the appropriate backend web server based on the
domain name used.

So yes, you can have a whole bunch of stuff running behind one public
IP address if you're willing to cope with the complexity.  But
sometimes life is simpler if you can use more.

Dear Richard Grainger,


I am grateful for your reply and guidance.


After reading the following article at nginx.com, I realize that I should use a
reverse proxy instead of a load balancer.


Article: WHAT IS A REVERSE PROXY VS. LOAD BALANCER?

Link: https://www.nginx.com/resources/glossary/reverse-proxy-vs-load-balancer/


Presently, I am using pfSense community edition firewall. Can I install the
Squid package and use it as a reverse proxy? Where can I find good installation
and configuration guides on this topic?


Based on what you have mentioned, it seems that reverse proxy can only be used
for HTTP and HTTPS protocols.


Can I use reverse proxy for DNS, IMAP, IMAP/S, POP3, POP3/S, SMTP and SMTP/s as
well?


So requests for domain1.com goes to all services/protocols in cPanel. And
requests for domain2.com goes to all services/protocols in Exchange 2016.


Is that possible? Please advise.


Thank you very much.
