We are now our own AS: AS-FREIFUNK-BERLIN (44194)
They are already given out if you use the config wizard. However, 
currently we have some issues with RPKI

Depending on the district of Berlin we give out "::/56".

On each gateway we except wireguard tunnels. I'm not sure about this hub 
and spoke topology. Per incoming connection request, we create a 
wireguard tunnel interface.

You have a global accessible "/56" Prefix. However, a firewall is 
running on the gateway. You need to configure it. We already have 
solutions for it (and working on better ones).
