IP
Address:
This
field
appears
when
NO
is
selected
for
“Obtain
Network
Addresses
via
DHCP”.
Specify
the
IP
Address
to
be
assigned
to
the
Ethernet
port
when
a
‘Static’
IP
Address
configuration
is
selected.
This
field
will
not
be
visible
or
accessible
when
a
‘Dynamic’
IP
address
configuration
is
selected,
as
the
DHCP
server
will
provide
the
Red
Lion
router
with
the
IP
address
that
it
should
use.
This
is
a
required
field.
The
IP
address
identifies
a
device
on
a
TCP/IP
network.
Every
device
on
a
network
must
have
a
unique
address.
The
range
of
valid
addresses
for
a
given
network
is
determined
by
the
value
of
the
Netmask.
Some
addresses
are
reserved
for
special
uses
such
as
network
and
broadcast.
For
example,
if
a
netmask
is
255.255.255.0
and
the
IP
address
assigned
to
the
device
is
192.168.1.3,
then
the
range
of
valid
addresses
is
192.168.1.1
through
192.168.1.254
as
192.168.1.0
is
the
value
reserved
for
the
network
and
192.168.1.255
is
the
value
reserved
for
the
broadcast
address.
Enter
Subnet
Mask:
This
field
specified
the
subnet
mask
to
be
assigned
to
the
Ethernet
port
when
a
‘Static’
IP
address
config
‐
uration
is
selected.
This
field
is
only
available
when
Obtain
Network
Addresses
via
DHCP
has
been
set
to
NO.
This
is
a
required
field.
Enter
Remote
Gateway:
This
field
specifies
the
IP
address
of
the
default
gateway
to
be
assigned
to
the
Ethernet
port
when
a
‘Static’
IP
address
configuration
is
selected.
This
field
will
not
be
visible
or
accessible
when
a
‘Dynamic’
IP
address
configura
‐
tion
is
selected,
as
the
DHCP
server
will
provide
the
Red
Lion
router
with
the
default
gateway
that
it
should
use.
If
specified,
the
Remote
Gateway
will
tell
the
Red
Lion
router
the
IP
address
of
a
router
to
which
the
Red
Lion
router
should
forward
all
traffic
for
which
it
does
not
already
know
a
specific
route.
Take
care
to
configure
only
one
interface
as
the
default
route.
Use
Remote
Gateway
as
Default
Route:
If
YES
is
selected
for
this
option,
the
Red
Lion
router
will
forward
any
packets
for
which
it
does
not
have
a
route
out
through
this
interface.
This
parameter
should
not
be
specified
if
the
Red
Lion
router
will
have
another
interface
with
a
default
route.
Use
Peer
DNS:
Select
YES
to
allow
the
interface
to
obtain
DNS
Server
settings
via
DHCP.
This
field
is
only
available
when
Obtain
Network
Addresses
via
DHCP
has
been
set
to
YES
.
Select
NO
to
allow
the
interface
to
use
the
DNS

the
Networking

DNS
Settings
screen.
The
recommended
setting
for
this
field
is
YES.
Enter
Maximum
Transmission
Unit
(MTU):
In
computer
networking,
the
Maximum
Transmission
Unit
(MTU)
of
a
com
‐
munications
protocol
of
a
layer
is
the
size
(in
bytes)
of
the
largest
protocol
data
unit
that
the
layer
can
pass
onwards.
MTU
parameters
usually
appear
in
association
with
a
communications
interface
(NIC,
serial
port,
etc).
Standards
(Ethernet,
for
example)
can
fix
the
size
of
an
MTU;
or
systems
(such
as
point
‐
to
‐
point
serial
links)
may
decide
MTU
at
connect
time.
A
larger
MTU
brings
greater
efficiency
because
each
packet
carries
more
user
data
while
protocol
over
‐
heads,
such
as
headers
or
underlying
per
‐
packet
delays,
remain
fixed;
the
resulting
higher
efficiency
means
a
slight
improvements
in
bulk
protocol
throughput.
A
larger
MTU
also
means
processing
of
fewer
packets
for
the
same
amount
of
data.
In
some
systems,
per
‐
packet
‐
processing
can
be
a
critical
performance
limitation.
However,
this
gain
is
not
without
some
downside.
Large
packets
can
occupy
a
slow
link
for
some
time,
causing
greater
delays
to
following
packets
and
layer
(and
hence
over
most
of
the
Internet),

about
one
second.
