How do you define "Firewalled"?
Do you mean simply UDP firewalled, or TCP firewalled, or other protocol? Or do you mean blocking via other means?
I suspect UDP or TCP firewalling would be a legal breach of services offered, potentially making an entity at risk of being sued be it the ISP or government being the target of such action.
You also need to consider proxy use and VPN's (although probably not so many people want to invest in VPN use, which costs, but can be very good.) |
