 their servers. This allows having a set of Nomad servers that service clients
 that can be spread geographically over a continent or even the world in the case
 of having a single "global" region and many datacenter.
+
+## Ports Used
+
+Nomad requires 3 different ports to work properly on servers and 2 on clients,
+some on TCP, UDP, or both protocols. Below we document the requirements for each
+port.
+
+* HTTP API (Default 4646). This is used by clients and servers to serve the HTTP
+  API. TCP only.
+
+* RPC (Default 4647). This is used by servers and clients to communicate amongst
+  each other. TCP only.
+
+* Serf WAN (Default 4648). This is used by servers to gossip over the WAN to
+  other servers. TCP and UDP.
