Networking – Remote Desktop Client Connection – Can Connect Via Cell Phone, Cannot Via Landline + ASUS Router + Public, Static IP

I want to connect from home to Windows Server desktop using the Remote Desktop Connection client.

  1. When I connect my laptop to the network using my cellphone, it works like a charm – I connect successfully and it works.

  2. At home, I have a landline with a static public IP and an ASUS wireless router. Unfortunately bdzionk – each time I get a timeout.

Apparently my home router or network provider is doing something with RDP (other services are working as expected).

How to better diagnose and solve the problem?
