# Ports & IP addresses

This document indicates the IP and ports we are listening to - that is, where traffic is sent from customer-placed equipment. This should be used to identify the traffic and open for outgoing traffic - not to do port-forward in the firewall or the like. From which port the traffic comes varies greatly depending on the equipment.
