Idle Timeout:
Auto-disconnect
the
router
when
there
is
no
activity
on
the
line
for
a
predetermined
period of
time.
Detail:
You
can
define
destination
port
and
packet
type
(TCP/UDP)
information
that
will
not result
in
the
router
checking
the
timer.
It
allows
you
to
set
which
outgoing

and

MTU: Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers) that IP will
attempt to send through the interface.
RIP: RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
TCP MSS Clamp: This option helps to discover the optimal MTU size automatically. Default is enabled.
MAC Spoofing: This option is required by some service providers. You must fill in the MAC address that has been
specified by the service provider when it is required. Default is disabled.
Obtain DNS:
A
Domain
Name
System
(DNS)
contains
a
mapping
table
for
mapping
between
Domain
Names
and
IP addresses.
On
the
Internet,
every
host
has
a
unique
and
user-friendly
name
(domain
name)
such
as
www.helloworld.com
as
well
as
an
IP
address.
An
IP
address
is
a
32-bit number
in
the
form
of xxx.xxx.xxx.xxx,
for
example
10.0.0.2.
You
can
think
of
an
IP
address
as
a
telephone
number
for
devices on
the
Internet,
and
the
DNS
will
allow
you
to
find
the
telephone
number
for
any
particular
domain
name. As
an
IP
Address
is
hard
to
remember,
the
DNS
converts
the
friendly
name
into
its
equivalent
IP
Address.
You
can
obtain
a
Domain
Name
System
(DNS)
IP
address
automatically
if
your
ISP
provides
it
when
you logon.
To
use
this
automatically
supplied
DNS
check
the
Enable
box.
