"Geographical area" refers to something akin to a site (such as the Sidgwick Site, or Downing and New Museums Site). While inbound connections are normally blocked we permit them where clients are physically close enough to allow things like Bonjour/iTunes sharing/UPnP etc. to work.

Everything else permitted.

inbound from elsewhere - CUDN and janet/internet

All blocked (the firewall is stateful, so allows responses to connections originated by the client).
