I have a NAS and TV on this Shaw Hitron cable modem.
How do I configure the Hitron to prevent the NAS and the TV from accessing the WAN, yet still be available on the LAN?
The Hitron's customer login Firewall page only seems to support block MAC's on an all or nothing basis. In other words, it seems to only allow blocking a device from accessing LAN+WAN. The Hitron software seems very amateur.
