MAC source support in firewalld

[Thomas Woerner]

Hello,

here is a new branch that adds MAC source address support to firewalld:

https://github.com/t-woerner/firewalld/commits/source_mac

MAC sources can be used in rich rules and also as source bindings in 
zones. There is a limitation though with MAC source bindings in zones: 
Port forwarding and masquerading rules in the zones do not have an 
effect for the MAC sources.

Please give it a try and report the issues you are running into.

Regards,
Thomas
