Required ports for Consul to work properly

What was not clear from the consul docs HERE, ports required to be open on the server. Here is the list of errors seen - 

Error joining the cluster: dial tcp 192.168.59.18:8301: i/o timeout

2015/01/14 23:55:50 [ERR] agent: failed to sync remote state: rpc error: failed to get conn: dial tcp 192.168.59.18:8300: i/o timeout

Ports the consul requires are

• 8301 - RPC
• 8300 - TCP
• 8500 - HTTP
• 8600 - DNS (domain lookup)
