Alternate ports for port 80 for websites on home Windows Server

Question

I'm setting up a home web server and this is the configuration:
Comcast business modem with 13 static IPs.
Modem-firewall features are all disabled and its in passthrough mode
I'm using the EdgeRouter 12
The server is assigned an internal IP of 10.1.xx.xx

I have 6 different websites/6 different domains

I will need to configure them at NetworkSolutions associating each one of them with one of my static public IPs

In the EdgeRouter, I need to do port forwarding connecting my static IP to a specific port for each website.

they cannot all use port 80 and I have 6 websites, so 80, 8008, 8080 will not be enough.

How do I do this.
Thank you.

Answer 1

If you have 6 domain names, they can all use the same port. Just configure host headers in the iis bindings.

Now days you should use ssl and port 443.
