Outbound External RDP timing out when the Domain Firewall profile is applied

Hello

I am running into an issue where a Windows 10 computer will not allow outbound external RDP connection unless the Domain Firewall profile is turned off. They can RDP locally to computers on the domain OK. This is the first time we have needed this kind of connection as its needed to access a 3rd Party application.

I have been through all the RDP troubleshooting I can find. Changed the firewall rules to allow RDP and ports. Turned off the firewall.

But if the domain profile is applied it just times out.

Any thoughts or suggestions?

    Hi,

    Welcome to Q&A platform.

    Please make sure that ports 3389 and 443 was enabled from target machine side firstly.

    And then please make sure that the rule you created in firewall were applied for domain profile.

    Hi,

    Thanks for your feedback.

    If the issue is related to Domain profile of Windows Firewall, I would suggest you could check which rule in Domain profile will block the traffic----enable Audit Filtering Platform Packet Drop and then reproduce the issue, for more detailed methods, please refer to the following link:
