Reverse Proxy
Using this MediaWiki as an example, MediaWiki is an official Synology Package that uses the official Synology Web Station package.
Utilizing the Web Station package, we will assign the port to the MediaWiki service. In this example, I randomly assigned port 7250 as the HTTPS port.
So now that we know the port that we are listening to on the MediaWiki service, we need to use the Reverse Proxy to make it all work seamlessly.
When Setting up the Reverse Proxy through DSM, navigate to the following location:
Control Panel >> Login Portal >> Advanced >> Reverse Proxy
Anything we have coming into a subdomain on aquarian.biz needs to be rerouted to some type of service port. This is so we maintain the HTTPS functionality while not having to forward ports through the router.
