Trying to setup a wifi router, so that the wireless devices can only access a particular IP/port on the wired network.
On "BT Voyager" router all the devices connected to the router can talk to each other, even with a firewall rule of "block all protocols from all addresses to all addresses, inbound and outbound". Presumably its firewall only applies to connections going via the broadband/phone line?
Are there other brands of wifi routers which have better support for firewalling between the WiFi and Ethernet devices?
