sudo systemctl mask qubes-iptables
sudo systemctl stop qubes-iptables
sudo systemctl mask qubes-firewall
sudo systemctl stop qubes-firewall

Open file ~/fw-unload in a text editor of your choice as a regular, non-root user.

If you are using a graphical environment, run. Click = Copy Copied to clipboard! mousepad ~/fw-unload

If you are using a terminal, run. Click = Copy Copied to clipboard! nano ~/fw-unload

Add.
