I think I've found a solution: If you hover over the SSH port field, it will show you extra info on port format e. g. ":port" or "server:port". Since Remmina will create a SSH by default leading to localhost you have to set the target NX server to "localhost".
Basically apply same logic as if you were to create the tunnel by hand in a terminal. I have tested this by connecting to VNC server through SSH. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to remmina in Ubuntu. https://bugs.launchpad.net/bugs/1323484 Title: remmina won't work with ssh ports other than 22 Status in remmina package in Ubuntu: Confirmed Bug description: Assume an open ssh port on 6222.
