I have a Cloudmin master server running behind a dedicated PFSense firewall. I’m using 1:1 NAT to access the master and the KVM guests and everything is working perfectly well…except accessing the Graphical Consoles.
I can see the KVM guests have VNC started through the boot messages:
QEMU waiting for connection on: tcp:127.0.0.1:40000,server
However when accessing through Cloudmin I get the following error:
VNC has been configured on this system by Cloudmin, but the VNC server on port 5901 on host system MY_SERVER is not accessible. If it was just enabled, the system will need to be rebooted before VNC is available.
Are there any additional changes that I need to make to either the firewall or to Cloudmin in order to get this to work?
Thanks in advance for any pointers.
