Thanks a lot. 

Moving on to firewall configuration for IPv6 on the web GUI - who would be the right person to talk to in order to understand the architecture and structure of the code? Or do I need to reverse engineer the existing?

Does it make sense to add this to ipfire2 or should I focus on ipfire3?

Best regards

Michael
