firewall with port mapping for spiceproxy, change 3128 in the spiceconfig only

[paweljasinski]

hi,

my proxmox server is behind firewall. Firewall is configured to forward port 8006 to proxmox - the web console is accessible.
However due to policy firewall is configured to map port 4444 to port 3128.
In order to access the spice console, I download the spiceconfig file, quickly edit a port inside (3128->4444) and start virt-viewer
Is there anyway to adjust a port number provided in the spiceconfig?

Cheers
