I wonder if your ISP has an MTU issue. That would explain small packets getting through but not bigger ones. I don't recall offhand how to troubleshoot that but a quick google search should give it to you. You can probably test it pretty quick by setting a lowish mtu with a paragraph in /etc/network/interfaces as described in man 5 interfaces.
