hhmm.. sometime you may want to have windows XP as gateway instead of linux…

the reason might be varies.. depend on the current situation you’re having .

let’s start.

go to Start > run >

type regedit … press Ok.


something as below should appear..


browse to HKEY_CURRENT_MACHINE]\ regedit2.PNG

right click at IPEnableRouter -> Modify … change the value to 1.

as this pic.


i think have to reboot your machine after changing those registry before it can be

effective.. else log out and log in back also can work..

hmm.. now connect the U-Mobile or your modem to internet what so ever.


then.. need to setup internet connection sharing for this modem with other network device..

go to Start -> Connect -> All Connection


then..  i think just have to follow this sequence


this will assign the ip of to the selected network device straight away..

but if you want to change also can..

after clicking yes…

go back to the that network device properties..

at tcp/ip .. put in your desired ip.. and netmask.. but leave the gateway as blank..


from other pc.. can use this ip as gateway ip address.

from linux.. system-config-network..

set static ip.. and the ip of windows xp as gateway
