(7) Connection ID
Provided  by  your  ISP.  If  your  ISP  did  not  give  you  a  connection  ID,

(8) Disconnect after X….
The  disconnect  feature  is  used  to  automatically  disconnect  the  Router 
from  your  ISP  when  there  is  no  activity  for  a  specified  period  of  time. 
For  instance,  placing  a  check  mark  next  to  this  option  and  entering 
“5”  into  the  minute  field  will  cause  the  Router  to  disconnect  from  the 
Internet  after  five  minutes  of  no  Internet  activity.  This  option  should 
be  used  if  you  pay  for  your  Internet  service  by  the  minute.

Setting Custom DNS SettingsDNS  is  an  acronym  for  Domain  Name  Server.  A  Domain  Name  Server 
is  a  server  located  on  the  Internet  that  translates  URLs  (Universal 
Resource  Links)  like  www.belkin.com  to  IP  addresses.  Many  ISPs 
do  not  require  you  to  enter  this  information  into  the  Router.  The 
“Automatic  from  ISP”  check  box 
(1)  should  be  checked  if  your  ISP 
did  not  give  you  a  specific  DNS  address.  If  you  are  using  a  static  IP 
connection  type,  then  you  may  need  to  enter  a  specific  DNS  address 
and  secondary  DNS  address  for  your  connection  to  work  properly. 
If  your  connection  type  is  dynamic  or  PPPoE,  it  is  likely  that  you  do 
not  have  to  enter  a  DNS  address.  Leave  the  “Automatic  from  ISP” 
check  box  checked.  To  enter  the  DNS  address  settings,  uncheck  the 
“Automatic  from  ISP”  check  box  and  enter  your  DNS  entries  in  the 
spaces  provided.  Click  “Apply  Changes” 
(2)  to  save  the  settings.

Configuring your WAN Media Access Controller (MAC) Address
All  network  components  including  cards,  adapters,  and  routers, 
have  a  unique  “serial  number”  called  a  MAC  address.  Your  ISP  may 
record  the  MAC  address  of  your  computer’s  adapter  and  only  let  that 
particular  computer  connect  to  the  Internet  service.  When  you  install 
the  Router,  its  own  MAC  address  will  be  “seen”  by  the  ISP  and  may 
cause  the  connection  not  to  work.  Belkin  has  provided  the  ability  to 
clone  (copy)  the  MAC  address  of  the  computer  into  the  Router.  This 
MAC  address,  in  turn,  will  be  seen  by  the  ISP’s  system  as  the  original 
MAC  address  and  will  allow  the  connection  to  work.  If  you  are  not 
sure  whether  your  ISP  needs  to  see  the  original  MAC  address,  simply 
clone  the  MAC  address  of  the  computer  that  was  originally  connected 
to  the  modem.  Cloning  the  address  will  not  cause  any  problems  with 
your  network.

Cloning your MAC Address
To  clone  your  MAC  address,  make  sure  that  you  are  using  the 
computer  that  was  ORIGINALLY  CONNECTED  to  your  modem  before 
the  Router  was  installed.  Click  the  “Clone”  button 
(1).  Click  “Apply 
Changes” (2).  Your  MAC  address  is  now  cloned  to  the  Router.
Entering a Specific MAC Address
In  certain  circumstances  you  may  need  a  specific  WAN  MAC  address. 
You  can  manually  enter  one  in  the  “MAC  Address”  page.  Type  in  a 
MAC  address  in  the  spaces  provided 
(3)  and  click  “Apply  Changes” (2) to  save  the  changes.  The  Router’s  WAN  MAC  address  will  now  be 
changed  to  the  MAC  address  you  specified.

Using  your  Internet  browser,  you  can  access  the  Router’s  Web-Based 
Advanced  User  Interface.  In  your  browser,  type  “192.168.2.1”  (do 
not  type  in  anything  else  such  as  “http://”  or  “www”)  then  press  the 
“Enter”  key.
You  will  see  the  Router’s  home  page  in  your  browser  window.
LAN Setup
Clicking  on  the  header  of  the  LAN  tab (1)  will  take  you  to  the  LAN 
tab’s  header  page.  A  quick  description  of  the  functions  can  be 
found  here.  To  view  the  settings  or  make  changes  to  any  of  the  LAN 
settings,  click  on  “LAN  Settings” 
(2)  or  to  view  the  list  of  connected 
computers,  click  on  “ DHCP  Client  List” (3).

Changing LAN Settings
All  settings  for  the  internal  LAN  setup  of  the  Router  can  be  viewed  and 
changed  here. 
(1) IP Address
The  “IP  address”  is  the  internal  IP  address  of  the  Router.  The  default  IP 
address  is  “192.168.2.1”.  To  access  the  advanced  setup  interface,  type 
this  IP  address  into  the  address  bar  of  your  browser.  This  address  can 
be  changed  if  needed.  To  change  the  IP  address,  type  in  the  new  IP 
address  and  click  “Apply  Changes”.  The  IP  address  you  choose  should 
be  a  non-routable  IP.  Examples  of  a  non-routable 
 
IP  are: 192.168.x.x  (where  x  is  anything  between  0  and  255)
 
10.x.x.x  (where  x  is  anything  between  0  and  255)
(2) Subnet Mask
ADVANCED  FEATURE!  There  is  no  need  to  change  the  subnet  mask.  It  is 
possible  to  change  the  subnet  mask  if  necessary.  Only  make  changes  to 
the  subnet  mask  if  you  specifically  have  a  reason  to  do  so.  The  default 
setting  is  “255.255.255.0”.
(3) DHCP Server
The  DHCP  server  function  makes  setting  up  a  network  very  easy  by 
assigning  IP  addresses  to  each  computer  on  the  network  automatically. 
The  default  setting  is  “ON”.  The  DHCP  server  can  be  turned  OFF  if 
necessary.  Turning  off  the  DHCP  server  will  require  you  to  manually  set 
a  static  IP  address  for  each  computer  on  your  network.  To  turn  off  the 
DHCP  server,  select  “Off”  and  click  “Apply  Changes”.

(4) IP Pool
The  range  of  IP  addresses  set  aside  for  dynamic  assignment  to  the 
computers  on  your  network.  The  default  is  2–100  (99  computers).  If 
you  want  to  change  this  number,  you  can  by  entering  a  new  starting 
and  ending  IP  address  and  clicking  on  “Apply  Changes”.  The  DHCP 
server  can  assign  100  IP  addresses  automatically.  This  means  that 
you  cannot  specify  an  IP  address  pool  larger  than  100  computers.  For 
instance,  starting  at  50  means  you  have  to  end  at  150  or  lower  so  as 
not  to  exceed  the  100-client  limit.  The  starting  IP  address  must  be 
lower  in  number  than  the  ending  IP  address.
(5) Lease Time 
The  length  of  time  the  DHCP  server  will  reserve  the  IP  address  for 
each  computer.  The  default  setting  is  forever,  meaning  that  any  time 
a  computer  is  assigned  an  IP  address  by  the  DHCP  server,  the  IP 
address  will  not  change  for  that  particular  computer.  Setting  lease 
times  for  shorter  intervals  such  as  one  day  or  one  hour  frees  IP 
addresses  after  the  specified  period  of  time.  This  also  means  that  a 
particular  computer’s  IP  address  may  change  over  time.  If  you  have 
set  any  of  the  other  advanced  features  of  the  Router  such  as  DMZ  or 
client  IP  filters,  these  are  dependent  on  the  IP  address.  You  will  not 
want  these  to  change.  We  recommend  for  this  reason  that  you  leave 
the  lease  time  set  to  “Forever”.
(6) Local Domain Name 
You  can  set  a  local  domain  name  (network  name)  for  your  network. 
There  is  no  need  to  change  this  setting  unless  you  have  a  specific 
advanced  need  to  do  so.  You  can  name  the  network  anything  you 
want  such  as  “MY  NETWORK”.  The  default  setting  is  “Belkin”.

Viewing the DHCP Client List Page
You  can  view  a  list  of  the  computers  (known  as  clients),  which  are 
connected  to  your  network.  You  are  able  to  view  the  IP  address (1)  of 
the  computer,  the  host  name (2)  (if  the  computer  has  been  assigned 
one),  and  the  MAC  address (3)  of  the  computer’s  network  interface 
card  (NIC).  Pressing  the  “Refresh” (4)  button  will  update  the  list.  If 
there  have  been  any  changes,  the  list  will  be  updated.

Configuring the Firewall
Your  Router  is  equipped  with  a  firewall  that  will  protect  your  network 
from  a  wide  array  of  common  hacker  attacks  including:
•   IP  Spoofing
•   Land  Attack
•   Ping  of  Death  (PoD) 
•   Denial  of  Service  (DoS)
•   IP  with  zero  length
•   Smurf  Attack
•   TCP  Null  Scan
•   SYN  flood
•   UDP  flooding
•   Tear  Drop  Attack
•   ICMP  defect
•   RIP  defect
•   Fragment  flooding
The  firewall  also  masks  common  ports  that  are  frequently  used 
to  attack  networks.  These  ports  appear  to  be  “Stealth”  meaning 
that  for  all  intents  and  purposes,  they  do  not  exist  to  a  would-be 
hacker.  You  can  turn  the  firewall  function  off  if  needed;  however,  it 
is  recommended  that  you  leave  the  firewall  enabled.  Disabling  the 
firewall  protection  will  not  leave  your  network  completely  vulnerable 
to  hacker  attacks,  but  it  is  recommended  that  you  leave  the  firewall 
enabled.
