Nodes accessible without Hole Punching

The Node uses port 7575. Connecting nodes will not do Hole Punching

Nodes on a local network

Nodes advertise themselves (without UUID) via udp broadcasts Needs to be more specific Nodes listen on port 7575. Any node on the network connects with that node but doesn't send its UUID. If there are multiple nodes on a device, only one will listen on port 7575 (the one, that started first).
