Hello I’m using Comodo Firewall on Windows 10 Pro 1607 for a long time without problems. Now I’m facing the problem that CF blocks any RDP connection to the clients it runs on.
I used to connect to this client via RDP maybe once or twice a week without problems. OK, first connection CF asked what to do and I allowed it. Then never touched the settings. Now, suddenly, it blocks RDP. Dont know when it worked the last time, maybe a month ago.
- Firewall is set to “Own Rules”.
- In Global Rules first two entries are “allow all to and from network called HOME” (both PCs are in this network)
- Tried to create an additional rule TCP IN FROM ANY TO ANY SOURCE PORT ANY DEST PORT 3389 - no change.
- Uninstalled CF and installed again with blank rules. But when trying to connect via RDP CF does not ask anyway.
- When switching CF to OFF, RDP works immediatly.
- Windows FW is turned OFF.
- Tried from different PCs (Win 7 and 10) to connect to this client with CF - same problem.
- Tried to change CF from “Own Rules” to “Training Mode” - no change.
Couldn’t find any forum entries with similar problems so created new topic.
Can any one help?
Thanks for every hint
