While our many services are partitioned into several containers with their own IP addresses, College only allocates us couple of IP addresses with permissive firewall rules, currently 220.127.116.11. and 18.104.22.168.
The following tables summarizes the external Internet access allowed to some hosts by the College firewall:
|22.214.171.124||cubemail||80, 443, 143, 110, 993, 587, 995||80, 443, 143, 110, 993, 587, 995|
|126.96.36.199||userweb||80, 443||80, 443|
|188.8.131.52||cubeirc||6667, 143||6667, 143|
|184.108.40.206||cube||22, 80, 443, 25, 113, 993, 6667, 53, 33434||Unfiltered|
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 220.127.116.11, but we do).
