## Building Consul
If you wish to work on Consul itself, you'll first need [Go](https://golang.org)
installed (The version of Go should match the one of our [CI config's](https://github.com/hashicorp/consul/blob/master/.circleci/config.yml) Go image).

Next, clone this repository and then run `make dev`. In a few moments, you'll have a working

**Serf WAN** This is used by servers to gossip over the WAN, to
other servers. As of Consul 0.8 the WAN join flooding feature requires
the Serf WAN port (TCP/UDP) to be listening on both WAN and LAN interfaces. See also:
