Bridge/WAN IP Bridge
When IP routing is active, the Express 4110/4120 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 4110/4120 can treat the WAN IP Bridge as a
virtual Ethernet port connected only to a WAN device which has negoti-
ated PPP BCP. This menu allows the IP parameters for this virtual Ether-
net 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 ver-
sion, 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 4110/4120 will proxy ARP on
the bridge IP port. See the section “IP/Proxy ARP” on page 3-21 for an
explanation of the proxy ARP function.

Bridge/WAN IPX Bridge
When IPX routing is active, the Express 4110/4120 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. How-
ever, if a device can only support PPP BCP, IPX packets are encapsulated
by the device as bridge packets. The Express 4110/4120 can treat the
