ATLAS 800 Series System Manual Router (IP)

Global

Proxy ARP Enables or disables Proxy ARP on this interface. Allows the network portion of

a group of addresses to be shared among several physical network segments.

When

ENABLED, and an ARP (address resolution protocol) 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 router answers the request with its own hardware address. When

DISABLED

(default), the router only responds to ARP request received for its own address.

The ARP protocol itself provides a way for devices to create a mapping between

physical (i.e., Ethernet) addresses and logical IP addresses.

PROXY ARP uses the

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

then correctly assumes 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.

Global

Write Security: 2; Read security: 2

Provides a way to configure various settings for the Ethernet port. The following menus are available for

review and editing:

Default Gateway Defines or changes the default gateway. Enter the default gateway address by

entering a decimal number into the appropriate field and then pressing <Enter>

to move to the next field. You will need a default gateway if the LAN contains

multiple segments. This address is composed of four decimal numbers, each in

the range of 0 to 255, separated by periods. This value is set to 0.0.0.0 by

default. Contact your LAN administrator for the appropriate address.

Default Metric Defines the default gateway metric. Enter the default gateway metric by

pressing <Enter> and entering a decimal number.

Default Gateway Cost Defines the default gateway cost. Enter the default gateway metric by pressing

<Enter> and entering a decimal number.

Ping

Write Security: 2; Read Security: 2

Allows you to send pings (ICMP requests) to devices accessible via the network. Only one ping session

can be active at a time.

IP Address Specifies the IP address to ping.

Count Specifies the number of pings to send. The maximum value is 99.
