Firewall settings for VirtualBox remote display

Written on

This post is about how to configure the Windows 7 firewall to allow VirtualBox Remote Display. I had a long running process running in a virtual machine that I wanted to monitor from another machine while I was working on other things. I started by opening the settings for my virtual machine and navigating to Display->Remote Display and enabling the server.

When I tried to use remote desktop from another machine on the same local network I was unable to connect. My first thought was to enable the Remote Desktop rules already present within the Windows Firewall.

However this also resulted in a connection error. To resolve the issue I had to allow VirtualBox to accept incomming connections.
