Troubleshooting Steps:

Disable UDP on Client (Advanced):

• This step might be necessary if firewalls or network configurations are causing issues.
• It's for users comfortable with Group Policy Editor.
• Open Run (Windows Key + R) and type gpedit.msc. Press Enter.
• Navigate to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client.
• Double-click Turn Off UDP on Client and set it to Enabled. Click Apply and OK.

Adjust MTU Size (if necessary):

• MTU (Maximum Transmission Unit): The largest data packet size transmitted on a network.
• The default Windows MTU (1500 bytes) usually works, but in rare cases, adjusting it might help.
• Caution: Changing MTU settings might affect other network connections.
• Consult your network administrator or internet service provider (ISP) for recommended MTU size if needed.
• Increase the MTU size gradually and test the RDP connection after each adjustment.

Prioritize VPN Traffic (if possible):

• This step optimizes your network for VPN traffic, potentially improving RDP connection stability.
• Note: This option depends on your router's capabilities.
• If your router supports VPN prioritization, look for settings in the router's web interface or command line interface (consult your router's manual).

By following these steps, you should be able to identify and address potential causes of RDP connection issues over VPN. Remember to proceed with caution, especially when modifying MTU settings, and consult a network administrator if needed.
