UDP Relay List/Relay Address

Write security: 3; Read security: 5

This is the IP address of the server that will receive the relay packet.

UDP Relay List/UDP Port Type

Write security: 3; Read security: 5

UDP Relay List/UDP Ports 1, 2, and 3

Write security: 3; Read security: 5

UDP Port 1, UDP Port 2, and UDP Port 3 are used for specifying UDP
ports to be relayed. These fields only apply when

UDP Port Type

»» IP/Proxy ARP

Write security: 4; Read security: 5

This feature allows the network portion of a group of addresses to be
shared among several physical network segments. 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 makes
use of this mapping feature by instructing a router to answer ARP re-
quests 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 to it. This technique effectively hides the
fact that a network has been (further) subnetted. If this option is set to

Yes

(def), 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 Ex-
press L128FP will answer the request with its own hardware address.

Standard
(def)

The following standard UDP protocols are relayed
when set: DHCP, TFTP, DNS, NTP (Network Time
Protocol, port 123). NBNS (NetBIOS Name Server,
port 137), NBDG (NetBIOS Datagram, port 138), and
BootP.

Specified

When set, the UDP port (1 to 65535) can be specified
in the UDP Port columns. (up to a maximum of three
per server)
