While the many services on cube are partitioned into several containers with their own IP addresses, College only allocates cube a single externally-routable IP address, currently, the IP address of the login container, cube.netsoc.tcd.ie. By using the login container as the externally-routable host, we ensure that users can SSH to cube transparently without having to concern themselves with our multiple IP setup.

The following tables summarizes the external Internet access allowed to and from cube by the College firewall:

IP address Host Inbound Outbound services.cubeirc None None admin None None cubemail 80, 443, 143, 110, 993, 587, 995 80, 443, 143, 110, 993, 587, 995 cubestorage None None cubewww None None userweb 80, 443 80, 443 cubeirc 6667, 143 6667, 143 cube 22, 80, 443, 25, 113, 993, 6667, 53, 33434 Unfiltered cuberoot None None ldap None None

Note that these are simply the ports which we can open on our own firewall without College intervention. This table does not reflect our own firewall configuration, and therefore does not indicate which ports are actually open at any particular time (for example, College doesn't filter outbound Internet access on, but we do).
