TO MAKE XP SYSTEM WORK AS A ROUTER

HOW  TO  MAKE  XP  SYSTEM  A  ROUTER

·         IP  FORWARDING  IS  A  VERY  GOOD  FEATURE  IN  WINDOWS  XP USING  WHICH  A  XP MACHINE  CAN  BE  MADE  TO  ACT  LIKE  A  ROUTER.  SO,  NEXT  TIME  YOU  SET  UP  HOME NETWORK  DO  CONSIDER  THIS.  SO  HOW  TO  DO  IT?  YOU  WILL  REQUIRE  AT  LEAST  2  OR  MORE  NIC  ( COMMONLY  KNOWN  AS LAN  CARDS )  TO  SETUP  THIS.
                                                               OR

·          ALTERNATIVELY  ON SECOND  NIC  YOU  CAN  CONNECT  A  SWITCH.  WHY  MULTIPLE NIC'S ?   ITS  OBVIOUS , 

·         1^ST  :  -  NIC  THAT  DIRECTLY  CONNECT  TO  INTERNET.

·         OTHER  :  -  NIC  WHICH  WILL  ACT  JUST  ANY  OTHER  INTERFACE  OF  ROUTER  HOLDING OTHER  NETWORK. ( IT  WILL  ALSO  ACT  AS  DEFAULT  GATEWAY)

LETS TAKE AN EXAMPLE, SEE FIG BELOW,

·         IN  THE  FIGURE  AS  YOU  CAN  SEE  THERE  ARE  3  NIC  ONE  OF  WHICH  CONNECTS DIRECTLY  TO INTERNET  OTHER  TWO  ARE  USED  AS  ROUTER  INTERFACE  TO  CREATE  DIFFERENT  NETWORKS . LETS  START  :  -

·         FIRST  WE  HAVE  TO  ENABLE  IP  FORWARDING,  TO  DO  THAT  :  -

·         GO  TO  RUN >  TYPE  REGEDIT  >  THEN  FOLLOW  PATH

  
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIPPARAMETERS

                             

·          RIGHT  CLICK  IPENABLEROUTER  REGISTRY  OBJECT, AND  CLICK  MODIFY

·         IN  THE  VALUE  DATA  FIELD  ENTER  1.  ITS  DONE  CLICK  OK.

·         NOW  CONFIGURE  THE  NETWORK  CARDS  ON  THE  XP  MACHINE  ( ROUTER )  WITH FOLLOWING  INFO  :  -

·         NIC – 2  :  -

                              NETWORK  CARD  A  ( CONNECT  TO  NETWORK A ) :
                              IP                                 :  10.10.10.1
                              NETMASK                  :  255.255.255.0
                              GATEWAY (GW)        :  [ LEAVE  IT  BLANK ]

·         NIC – 3  :  -  


                           NETWORK  CARD  B  ( CONNECT  TO  NETWORK  B ) :
                   IP                                :  192.168.20.1
                   NETMASK                  :  255.255.255.0
                   GATEWAY  ( GW )     :  [ LEAVE  IT  BLANK ]

·        NIC – 1  :  -

NETWORK  CARD  C  ( CONNECT  TO INTERNET  VIA  CABLE/DSL  CONNECTION )

THIS  INFORMATION  WILL  BE  BASED  ON  THE  INTERNET  CONNECTION  SERVICE  WHICH YOU  HAVE  SUBSCRIBED.

·         CONFIGURE  ALL  THE  COMPUTERS  IN  NETWORK  A  WITH  FOLLOWING  INFORMATION.

NETWORK  A
IP                                :  10.10.10.2-254
NETMASK                 :  255.255.255.0
GATEWAY (GW)       :  10.10.10.1

·         CONFIGURE  ALL  THE  COMPUTERS  IN  NETWORK  B  WITH  FOLLOWING  INFORMATION.

NETWORK  B
IP                    :  192.168.20.2-254
NETMASK      :  255.255.255.0
GATEWAY     :  192.168.20.1

THAT'S  IT  YOUR  DONE.
