The Linktropy WAN emulator can be installed as either a bridge or router to forward frames
between the LAN A and LAN B Ethernet interfaces. By default, the Linktropy WAN emulator is
configured as a bridge, and this mode is recommended for simplicity unless the LAN A and LAN B
interfaces need to be on separate subnets.

5.1 Bridging Mode
In Bridging Mode, the Linktropy device functions as a bridge between the Ethernet segments
connected to the LAN A and LAN B ports. In this mode, it can forward any Ethernet-based frame
regardless of network layer protocol. VLAN tagged frames (IEEE 802.1Q) are supported, but no
special action is taken based on VLAN.
