EasyVPN connectivity through firewalls

I have not tried EVPN yet, but have a question concerning connectivity before I do.

I understand that EVPN uses a central server to initiate connections, then ongoing connectivity is peer to peer. But what about if both clients are firewalled?

Does all traffic go through the central server, or does EVPN punch a UDP (or even TCP) hole through the firewall to create the peer to peer connection?

If both parties are not directly connectable, then the connection is maintained by relay through a Comodo server, the same way Hamachi did things.
