Section 4 SHDSL RCU ATM User Interface Guide Total Access 544R System Manual

ROUTER > CONFIG > INTERFACES (ETH) > SUB-INTERFACE

The Ethernet sub-interface is ATM[0.1]. The [0.1] represents the ATM physical and logical ports, when 0

is the physical port and 1 is the logical port assigned to the ATM interface. This a read-only field.

V2 SECRET

Enter the secret used by RIP version 2 here.

PROXY ARP

This feature allows the network portion of a group of addresses to be shared among several

physical network segments. The ARP protocol provides a way for devices to create a mapping

between physical addresses and logical IP addresses. Proxy ARP makes use of this mapping

feature by instructing a router to answer ARP requests as a "proxy" for the IP addresses behind

one of its ports. The device which sent the ARP request will then correctly assume that it can

reach the requested IP address by sending packets to the physical address that was returned. This

technique effectively hides the fact that a network has been (further) subnetted. If this option is

set to

YES, when an ARP request is received on the Ethernet port the address is looked up in the

IP routing table. If the forwarding port is not on the Ethernet port and the route is not the default

route, the unit will answer the request with its own hardware address. Default is

NO.

SECONDARY IPS

This allows the unit to specify additional IP addresses and networks on its Ethernet. The maximum

number of entries is 5.

NUM

Displays the index number in the secondary IP list.

IP ADDRESS

This is the second IP address the unit will respond to on the Ethernet. Default is 0.0.0.0.

SUBNET MASK

This is the mask for the network. Default is 255.255.255.255.

NAT MODE

This mode specifies whether Network Address Translation (NAT) should be use on this

interface. When this mode is set to

PRIVATE (def) NAT is automatically specified on this

interface. The other choice is

PUBLIC which specifies not going through NAT.
