Firewall rule by MAC address

Hi everyone,

I have a network TV tuner (HDHomeRun) that uses random port on the network.

So, in order to be able to use it from YunoHost I have to manually add an iptables rule like that:
sudo iptables -A INPUT -m mac --mac-source 00:11:22:33:44:55 -j ACCEPT.

Any possibility to improve the YunoHost firewall CLI in order to add a feature to allow a specific MAC address?

Thank you!
