How do you block those servers with a Linksys router? I assume it's within the Access restrictions tab of the router's address, but I'm not sure where to go from there. If I enter it under "website blocking" then I'm only allowed to block 4, but I'm not sure if that's even it. I also see where I can block ports, but it looks like that's designed only to enter a range of numbers, not these addresses. Thanks if you can help.
