Previously I was starting a Windows VM to do nothing else but connect to other Windows machines or VMs using Remote Desktop Gateways. Several weeks ago I was asked why I don’t use Remmina as it uses FreeRDP and this has the feature implemented. With a quick search I found an answer (from 2014) that I would have to compile FreeRDP myself. It was also mentioned that there was a feature request on the Remmina GitHub repo which one should upvote. There I found the information that it was already implemented …
So I double-checked if I was running the current version of Remmina. The Linux Mint Update Manager also did not show any updates.
Remmina was installed in version 1.1.2 – support for Remote Desktop Gateway was added in version 1.2.0 (which is currently available as PreRelease).
The wiki mentions that there is an official PPA for Remmina 1.2 which one can add and install the latest PreRelease with the following commands:
sudo apt-add-repository ppa:remmina-ppa-team/remmina-next sudo apt-get update sudo apt-get install remmina remmina-plugin-rdp remmina-plugin-gnome libfreerdp-plugins-standard
After updating Remmina with the latest PreRelease I can now successfully connect using RDG without firing up a VM every time.
