I'm replying to this post because it describes exactly what I am experiencing.
I have had Avast Firewall working great, but then I received an Avast program update and I'm assuming something was changed in my environment.
In a nutshell,
1. I have the firewall turned on.
2. In the settings I have allowed Remote Desktop Connections.
3. In the application rules, I have added a line for TCP/UDP in from port 3389
4. In the Geek:area I have Internet Connection Sharing mode enabled, as well as "Allow all connections with Friends". The other flags in the Firewall area are turned off.
5. My Network connections are private.
6. I can rdp in when I am doing so from within my own network.
7. I can rdp in from outside my network only when I turn off the Avast Firewall.
8. I also do not get any blocking entries in my firewall log.
9. Both of the systems I am using are windows 10.
Very Frustrating.. Any ideas/thoughts are appreciated..
Thank you.
Hi,
You mentioned that it only occurred after the update.
I would suggest that you "Restart" (not reboot) your PC.
If you have already done so and are still experiencing the issue, please post a support file id here or PM me.
Please follow these steps:
1. Open - Avast Premium Security > Click on - Menu > Settings > General > Troubleshooting > Select - Enable debug logging (at the bottom)
2. Please try to connect again to the PC in question.
3. Please generate the support file and reply with the support file id.
