Chapter 4: Configuration Overview

Bridge/WAN IP Bridge

When IP routing is active, the Router Option Module will allow an- other WAN device to bridge IP packets to itself by 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 en- capsulated by the device as bridge packets. The Router Option Module can treat the WAN IP Bridge as a virtual Ethernet port con- nected 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 Router Option Module will proxy ARP on the bridge IP port. See the section IP/Proxy ARP on page page 4-9for an explanation of the proxy ARP function.

Bridge/WAN IPX Bridge

When IPX routing is active, the Router Option Module 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 support only PPP BCP, IPX packets are encapsulated by the device as bridge packets. The Rout- er Option Module can treat the WAN IPX Bridge as a virtual Ether-
