I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Assuming its not a misconfigured firewall, I would bet dns is handing you a public IP even when you are internal. Check with nslookup
AND your router doesn’t like hairpin routing: when hitting a public IP that is port forwarded to an internal IP address
Do you have an internal DNS server? You need to add an “A record” for shop.mystore.com to the internal IP of the server.
Or if this server is just hosting one website, change the binding to “*”, and use the internal IP when you are internal.
