Ports used by the failover system

Created by Yulia Morozova on Dec 04, 2023

Each failover system server uses the following ports:

4000 (Supervisor Web-Interface, only TCP),
4646 (Nomad HTTP API, only TCP),
4647 (Nomad RPC, only TCP),
4648 (Nomad LAN/WAN Serf (Gossip), TCP and UDP),
8300 (Consul Server RPC, only TCP),
8301 (Consul LAN Serf (Gossip), TCP and UDP),
8302 (Consul WAN Serf (Gossip), TCP and UDP),
8500 (Consul HTTP API, only TCP),
8600 (Consul DNS, TCP and UDP).

Moreover, each node of the cluster has its pre-defined unique port range (see Installation).
For best results, use port numbers from 20111 to 32000.
