If you are sitting at your company office or are in a college, chances are that all or most of your traffic is monitored or blocked. Also if you are on LAN, then its quite probable that you access most of your internet using a single proxy sitting behind a NAT.
The downside, well limits to everything. In my own campus while just being unable to browse the simplest sites such as gamespot.com or bash.org, theres also limits on download filesizes [permissible limit being 75Mb]. To add to the discomfort, access on any port save 3128 or 80 is blocked, disabling access to torrents, p2p networks, mmorpgs or even NTP servers.
However, there is still a bypass. Well for the simpler things such as anonymity and freedom over browsing the net can be achieved using a tunneler such as Freedom[www.your-freedom.de] or Jap[http://anon/inf.tu-dresden.de/index_en.html]. All one needs to do is install the software, edit the configuration to specify their connection settings and choose a suitable server. Change your browser settings to use a proxy running on localhost at a port of your own choice.
For other things like running WoW behind the NAT/proxy, things notch up another tiny bit. Apart from a proxy software supporting either Http connect requests or allowing socks 4/5 connection (both Freedom and HTTP-Tunnel [www.http-tunnel.com] are good for this), another nifty software, Proxifier [www.proxifier.com] is needed. Simply putting it, Proxifier works like a translator taking all internet traffic from WoW and routing it to the proxy. To the game Proxifier remains invisible and hence faking a direct connection to the net. The same setup can be used to run applications like Bittorrent, Instant Messengers, Windows time or anything else needed a direct internet connection.
