How can I enable remote requests in IIS Express? Scott Guthrie wrote that is possible but he didn\'t say how.
You may try setting up port forwarding instead of trying to modify your IIS Express config, adding new HTTP.sys rules or running Visual Studio as an Admin.
Basically you need to forward the IP:PORT
your website runs at to some other free port on your machine but on the external network adapter, not localhost.
The thing is that IIS Express (at least on Windows 10) binds to [::1]:port
meaning it listens on IPv6 port. You need to take this into account.
Here is how I made this work - http://programmingflow.com/2017/02/25/iis-express-on-external-ip.html
Hope it helps.
