通過註冊表修改RDP Port後無法連上

Question

我的電腦所有端口都是開放的 在路由器設定為橋接模式

所以想通過修改端口號提升安全性 但是我的電腦只有在預設端口(3389)才能連上

改為其他端口(3390)則無法連上

我有嘗試在本地啟動Django Server並將端口改為 3389 3390 等皆可連上Django Server

只有RDP連不上

我有自己的網域名稱 還是能禁止所有以IP連線的要求 只同意以網域名稱連線

Title:Cannot connect after changing RDP Port through registry.

All the ports on my computer are open and the router is set to bridge mode.

So I want to improve security by changing the port number, but my computer can only connect on the default port (3389).

Changing to another port (3390) does not work.

I have tried to start Django Server locally and change the port to 3389, 3390, etc. and they can all connect to Django Server.

Only RDP cannot connect.

I have my own domain name. Can I block all requests that connect by IP and only allow connections by domain name?

Hello @周恭煥

Here are some things you can check:

1. Did you specify the port number after the IP address?  For example, if the IP address of the remote computer is 192.168.1.100 and you have changed the RDP port number to 12345, you would enter 192.168.1.100:12345 in the Remote Desktop Connection window to connect to the remote computer.
2. Check if the server is listening on the new RDP port number: netstat -an | find "12345"
3. Check if the Remote Desktop Services is running on the server.
