Given a public WiFi hotspot behind an ISA Sever and a single Internet address, which rules or content filters would be useful to achieve this configuration?
Allow anonymous users to surf the web, chat over IM, and connect to their different workplace VPNs
Restrict Bittorrent and other P2P clients from attracting the attention of MediaSentry and others.
What sort of tests will show if an ISA firewall policy is sufficient? For example, with the uTorrent client, you can configure the port used (for incoming connections?), so will changing to port 80 show you if P2P traffic is getting through?
The top P2P networks appear to be Bittorrent, DC++, eDonkey and Usenet.
