The FVS124G VPN Firewall incorporates Auto UplinkTM technology (also called MDI/MDIX).
Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the
port should have a normal connection (e.g. connecting to a PC) or an uplink connection (e.g.
connecting to a router, switch, or hub). That port will then configure itself to the correct
configuration. This feature also eliminates the need to worry about crossover cables, as Auto
UplinkTM will accommodate either type of cable to make the right connection.
