there is an ongoing thread at the moment on thinkbroadband about this.

its emerged ukonline/easynet are using some kind of filtering proxy for http traffic, but there is a little dispute into what the proxy is actually doing. Since sky also use easynet its likely the same is applying to both sky and ukonline.

My assumption is easynet are routing ips that are known to have hosted illegal content via their filtering proxy so they can filter out illegal content, eg. so they can enforce the IWF list. Rapidshare is probably one such site that hosts that kind of content so it is filtered via the proxy.

The problem that has arisen is that rapidshare are not using the x-forwarded-for header and as such using the proxy ip instead of the end user ip and banning for reasons such as wrong password flooding.

One user on thinkbroadband claims easynet are proxying everything and not doing any filtering but I see no evidence suppporting that and I feel its more likely just a few specific ip addresses get routed via the proxy.
