We have had SC for a while now and all was peachy and running well on the installed default ports 8040/8041 until...

Some of our customers are locked down to only accept traffic on ports 80 and 443. I have been tasked with switching this over to these ports.

My problem is, We already have something running on our server on port 443 and it cannot be moved. My imagined solution was to leave the relay running on 8041 on the internal server, and forward it to 443 on a new external IP (443 is in use internally and externally on our main IP).. This is not working, because there is only one place to specify a URL:port in the config file for relay, and I can't set it to both 8041 and 443.

How can I get SC relay to run on 8041 internally, but on 443 externally?

Thanks for your help.

PS - here's a little visual of my port forwarding

BEFORE -

InternalIP:8040 -> ExternalIP:8040
InternalIP:8041 -> ExternalIP:8041

DESIRED -
InternalIP:80 -> ExternalIP2:80
InternalIP:8041 -> ExternalIP2:443

Most routers allow in the port forwarding section to specify external and internal ports. This way you can specify 443 on the external side and 8041 on the internal side.

Now the problem arises where you have internal SC guests that are programmed for the internalip:8041. They would need to be changed to externalip:443 and you need to make sure your router supports loopback.

Now with windows you can add more than 1 ip address to a network card. Then you could change the SC relay port to 443 and bind it to the specific ip address. The other service running on 443 would also have to be specified to bind to the original specific ip address.
