[PVE-User] How to VNC to VM from Windows 10 to Proxmox VM behind masquerade IP

[Usama Ahmad]

May I suggest using

args: -vnc 0.0.0.0:104

In #cat /etc/pve/qemu-server/104.conf or other configs

The above 'arg' will open direct vnc to 5900+104=6004 on your proxmox host.

Hope this helps.
Sorry for bad formatting using phone.
