Hi, A few days ago I got ADSL2+ and I’m messing around with port forwarding and different settings on the router. Whenever I change the MTU to something around 1350 (or anything less than 1500) the speed improves a lot but I can no longer access kirupa or MSN. All other sites I can still get to without a problem.

What’s with that?
