connection basically disables the routing, firewall and NAT features of the 4-port Wireless N Gateway. In a
1483 Bridged connection, the 4-port Wireless N Gateway acts as a modem or hub, and just transmits packets
between the WAN interface and the LAN interface. A 1483 Bridged connection assumes that another device
is providing the routing functionality that is now disabled in the 4-port Wireless N Gateway.
