Seems like I can install nginx on a virtual machine and port forward from my pfsense firewall to it, according to the following article.

Hi, Based on further research, it appears that Squid can only reverse proxy HTTP and HTTPs but NGINX is able to reverse proxy IMAP, POP3, and SMTP protocols. Please correct me if I am wrong. Thank you. ===BEGIN SIGNATURE=== Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ <https://tdtemcerts.wordpress.com/>[2] http://tdtemcerts.blogspot.sg/ <http://tdtemcerts.blogspot.sg/>[3] https://www.scribd.com/user/270125049/Teo-En-Ming <https://www.scribd.com/user/270125049/Teo-En-Ming>===END SIGNATURE=== ________________________________ From: Turritopsis Dohrnii Teo En Ming Sent: Saturday, July 21, 2018 1:18 AM To: CentOS mailing list Cc: Turritopsis Dohrnii Teo En Ming Subject: Re: [CentOS] Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP? 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. ===BEGIN SIGNATURE=== Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ [2] http://tdtemcerts.blogspot.sg/ [3] https://www.scribd.com/user/270125049/Teo-En-Ming ===END SIGNATURE=== ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Richard Grainger <grainger at gmail.com> Sent: Saturday, July 21, 2018 12:29 AM To: CentOS mailing list Subject: Re: [CentOS] Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP? 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.

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.
