RX (
DEF
)
RIP advertisements are periodically transmitted and are listened to on this port.
TX O
NLY
RIP advertisements are periodically transmitted but are not listened to on this port.
RX O
NLY
RIP advertisements are listened to on this port, but are not transmitted on this port.

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
Y
ES
,
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
N
O
.
S
ECONDARY
IP
S
This allows the unit to specify additional IP addresses and networks on its Ethernet. The maximum
number of entries is 5.
N
UM
Displays the index number in the secondary IP list.
IP A
DDRESS
This is the second IP address the unit will respond to on the Ethernet. Default is
0.0.0.0
.
S
UBNET
M
ASK
This is the mask for the network. Default is
255.255.255.255
.
NAT M
ODE
This mode specifies whether Network Address Translation (NAT) should be used on this
interface. When this mode is set to
P
RIVATE
(default) and NAT is enabled for the unit, packets to
and from this interface are translated. If set to
P
UBLIC
, packets to and from this interface will not
be translated through NAT.
