I have a block of IP addresses that my data center provides to me. I am currently using one of them as the WAN IP on my Mikrotik router. I need to use the others on a single web server, as Apache requires that you use a separate external IP address for each SSL certificate. I want to keep the server behind my Mikrotik firewall, but I need to somehow map the external IP addresses to the internal server.
I understand that I can use this tutorial to route the external IPs to internal IPs, but I need Apache to use the external IPs rather than internal ones at the server level.
What is the best way to give my web server external IP addresses while remaining behind my Mikrotik firewall?
