For people needing to block ports & URL(s) and have no way of doing it on their router itself. You can always use a free software firewall (like this one: http://www.personalfirewall.comodo.com/
Only downside to this method is that it's a per-PC situation, where as doing the changes on the router/gateway will make it work for all PC's on the network instantly.
I wonder if this will work for other media sites like Pandora, Netflix US, etc? That would be great if so. Otherwise a private VPN is still not a bad way around either.
Either way, thanks for this!
