    If you're on a university campus you'll have a big external firewall because the university will be sitting behind a big NAT, so you're probably good.

    A lot of University networks won't actually be behind a NAT at all, because they were the ones who got the initial set of Class B networks, so often they're actually handing out publically addressable IP ranges internally (they really should and probably are firewalled these days, however).

    That said, it's probably unlikely in most cases that there is much in the way of internal segregation between student residences, so it's definitely worth making sure your machine is treating the university network more like a public network than a private one.
