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 L128/L128T 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.
WAN IP Bridge/Network
Write security: 2; Read security: 5
This is the IP address of the virtual Ethernet port.
WAN IP Bridge/Netmask
Write security: 2; Read security: 5
This is the network mask to be applied to the virtual Ethernet port.
WAN IP Bridge/Triggered
Write security: 2; Read security: 5
When set to Yes, only IP RIP updates are sent when the routing table has
changed. When set to No (def), updates are sent periodically. RIP version,
method, and direction are determined by the Ethernet parameters set in the
Configuration/IP/IP Router/RIP menu.
WAN IP Bridge/Proxy ARP
If this option is set to Yes (def), the Express L128/L128T will proxy ARP on the
bridge IP port. See the section IP/Proxy ARP on page 46 for an explanation of
the proxy ARP function.
Bridge/WAN IPX Bridge
When IPX routing is active, the Express L128/L128T will allow another WAN
device to bridge IPX packets to it using PPP BCP. Normally, two IPX routers
would negotiate PPP IPXCP to exchange IPX packets. However, if a device
can only support PPP BCP, IPX packets are encapsulated by the device as
bridge packets. The Express L128/L128T can treat the WAN IPX Bridge as a
virtual Ethernet port connected only to a WAN device which has negotiated
PPP BCP. This menu allows the IPX parameters for this virtual Ethernet to be
setup.
