Hello Microsoft community,

I need advise or to be pointed to the right direction.

I have 2 desktops at home,

I have one set with 3389 as the port for the firewall rule - PC1

I have the other one set with 3388 as the port for the firewall rule - PC2

I am using my external ip in RDP to access PC 1 and I can access it

(I port forwarded port 3390 and the ip for PC 1)

I did the same for port forwarding port 3388 and the ip for PC 2 - but no luck

The problem is when I try to access pc 2 using my external pc, I change the user name to the 2nd pc and put the password, I get a kick back saying the credentials dont match.

So I know im doing something wrong. But I cant figure it out :(

Here is what I want:
I want to access both pc's using the same external ip in RDP.
Im outside the network of the two pc's.

Please advise!

Thank you

    Then something else is broken or misconfigured. Try using the private address on LAN (PowerShell)

    Test-NetConnection -ComputerName "192.168.10.10" -Port 3390 -InformationLevel "Detailed"

    then when successful try again using the public facing address but from internet.

    Try access them each by using the following format

    10.155.46.120:3390

    10.155.46.120:3388

    (sub your actual public facing ip address above)

    Thank you for that Powershell command, This issue was on my end of the router side, it was misconfigured wrong, I had the wrong port. I put the correct port on my end for port fowarding and re-ran the command and it gave me and answer.

    I rdp using <External Ip>:Port number (eg 192.168.10.10:3387)
    and I was able to connect to the 2nd computer,

    I repeated the same steps for the first computer and worked.

    Thanks for the help.
