Hello, this post gonna be simple and straight – About ESET Smart security. This post should help get you fix that connectivity issues; you were trying to establish a remote desktop session to your desktop/laptop at your home from internet, remotely. You might be using Static Public IP or best utilizing that Dynamic IP with the DDNS services (comment if you would like to see how to use DDNS service to get into your home computer RDP).
For some reasons, ESET isn’t allowing the MSTSC application/3389 port white-listing when you manually setting this up in Advanced settings Or maybe let me put it this way, when you setup the port/mstsc application traffic white-listing, it isn’t working as expected :(. So, firewall Interactive mode to the rescue.
It is very important that you stop all the Internet activity on your Home computer, to avoid getting multiple questions asked by the ESET for network communication. Example: Web browsing and other computer activity stoppage should help you avoid random questions being asked.
Click on “Setup” of ESET smart security and then “Enter Advanced Setup” -> Expand “Network” And then Click on “Personal Firewall” and then change the Filtering mode to “Interactive mode” and then click “OK”
Now try to initiate the Remote desktop from Internet to your computer, and then you will get a pop-up in ESET asking if you want to allow or Deny MSTSC.EXE application traffic. Click on Allow, and then once done establishing the session to your computer, change the ESET Firewall settings to “Automatic mode” from “interactive mode”
This helps you avoid answering all the network communications filtering questions again.
