Dear all, I have a problem with some sites. I am within a school network which has always had WebMarshal installed, but there was a Python program which most of us had which was not only able to get past WebMarshal and go onto any site, but also let us use MSN Messenger. To make it work you had to change the LAN Settings to listen on localhost (this computer) on port 4463. The server is a Microsoft Exchange Server with a SOCKS 5 proxy, and last night the admins must have changed some rules and blocked some ports or something like that because today nothing works, and I cannot even buy things from Amazon.co.uk. This is a College, and even though we already have 10 people in our year writing a new program as we speak to get past the filter, I would like to know what is going on. The filter blocks offensive sites, https sites, POST, and it also says "Blocks non-business sites". Any ideas? Thanks in advance,

D Cheng
