When this option is set to On (def), the Express L768 bridge function
will be enabled. Setting it to Off will disable all bridge functionality.
»» Bridge/WAN IP Bridge
When IP routing is active, the Express L768 will allow another WAN
device to bridge IP packets to it using PPP BCP. Normally, two IP
routers would negotiate PPP IPCP to exchange IP packets. However,
if a device can only support PPP BCP, IP packets are encapsulated by
the device as bridge packets. The Express L768 can treat the WAN IP
Bridge as a virtual Ethernet port connected only to a WAN device
which has negotiated PPP BCP. This menu allows the IP parameters
for this virtual Ethernet to be set up.
