Mike lives in a remote area and he usually accesses the Internet via his mobile phone. He also has point-to-point internet, which is not only expensive, but he's concerned with security because the service requires a router connection in bridge mode with DHCP. Leo says that routers can be secure as long as he connects with encryption via WPA2. Routers are essentially dumb boxes that can protect him from attacks. But that depends on how they handle their security. It can be just as secure as his home network, or it can be wide open. It might be worth calling the host and asking them what they're doing and why.
