In order to connect remotely to a RDPlus server, you will need to disable your windows firewall or set an inbound and outbound rule to accept RDPlus connections.
Disabling the Windows Firewall can be a good choice if you already have an external firewall on your ISP router, it can be disabled easily this way :
Click on the start menu, go to Control Panel, System and Security, Windows Firewall. Then click on “Turn Windows Firewall on or off”.
Then click on :”Turn off Windows Firewall”.
If you choose to create a Windows Firewall rule to accept inbound and outbound connection, this is how to do it :
Make sure to turn on your firewall first.
Click on the start menu, go to Control Panel, System and Security, Windows Firewall. Then click on “Advanced settings”.
Click on “Inbound Rules”, then click on “New Rule” :
Click on “Port”, then click “Next.
Click on “Specific local ports”, if you want to use connect to a RDPlus server using RDP you will need to fill in this field with 3389 and/or 80 and/or 443 for the use of secured TSWeb. Note that RDPlus and TSWeb use TCP protocol only.
Then click next.
Make sure “Allow the connection” is selected, then click next.
Make sure all boxes are checked, then Click next.
Type in a name for this new firewall rule, RDPlus for example. Then click “Finish”.
Now that the inbound rule has been made, you will have to repeat this exact process for the outbound rule.
