Since Hamachi uses UDP traffic to create the peer to peer tunnels, some environments may be difficult to get Hamachi connected between peers.

In cases where you are in a very restricted environment, having UDP 17771 Outbound allowed on the firewall will allow the machines inside the firewall to get a relayed connection to the mediation server (and thus peers).

Since UDP is locally a random protocol controlled by the operating system, the only other way to allow only a single port for the direct peer to peer connectivity is to set a static port on the other peer(s) and allow that port outbound on the firewall.
