I've written an asmx web service and am working on hosting it via IIS. I've added port bindings to my domain and I am able to access it externally by visiting my domain without issue.
The problem I'm having is that I can't use the default port 80 to host the web service, which I need to do because of limitations with mapping to specific ports.
Whenever I access the default port I'm redirected to my WD MyCloud website, basically the url is automatically appended with /UI (www.mydomain.com redirects to www.mydomain.com/UI)
As far as I can tell I don't have any DNS records that are pointing to that internal IP address and I don't have any http rewrites that would be sending traffic to that URL.
At this point I don't know if it's a router issue, a DNS issue, an IIS issue or possibly something else. I'm not even sure how to troubleshoot it to find out where this URL is coming from.
The only sure thing I can say is that when I log into my Linksys router and turn on the "Filter Internet NAT redirection" option, the redirects no longer happen and I am sent to the Linksys web URL, but none of my ports forward at that point.
