Internet Sharing \w Wireless Belkin Router, Win XP & ZyXel Modem

I have one computer that is on all the time and several others. The one
that is on all the time is connected to the internet via a ZyXel Modem
connected to the USB port. The goal now is that all other computers can
use that internet connection. What I did so far is

1) Connecting the computer that is always on to one of the LAN ports on
the wireless Belkin Router.
2) To start with I also did connect one laptop to another LAN port (the
final goal is going wireless) on the router.
3) The router has it's DHCP enabled and has the IP address
192.168.0.128.
4) Both computers are on the same group (WORKGROUP).
5) For the computer that is always on I enabled internet sharing for
the ZyXel broadband connection.

>From both computers I can go to the routers setup page. I can also ping

each computer from the other. I cannot access the internet from the
laptop, though. Maybe an other important note is that on the computer
that is always connected I get a ZyXel broadband connection AND when I
am connected as LAN2 (on top of the LAN) connection with limited
functionality. Don't know where that comes from but from that computer
I have no problems getting on the internet. Any ideas what I did wrong
or that I am missing?

Thanks

The first thing you need to do is get the router connected to your Internet
connection directly, then get all PCs connected to the router. You could
turn off all the router functions and use it as a simple switch, using ICS
on the "always-on" PC to share the connection but I would not recommend it.

You have a few problems here. First of all, you have 2 DHCP servers
going, because part of the ICS functionality in WinXP is a DHCP server.
See http://support.microsoft.com/kb/306126/ By default, and
without the ability to be changed, the network adapter that is connected
to the LAN is configured with a static IP address of 192.168.0.1 and a
subnet mask of 255.255.255.0.

Access the router's configuration pages and turn off the router's DHCP
server. Change the router's IP address to something on the same subnet
that's unlikely to conflict with the IPs of the other computers, e.g.,
192.168.0.175.

That's about it, although you could also set the computers on your
internal network to use static IPs in the 192.168.0.xxx range. If you
don't they will be assigned such IPs by the ICS DHCP server.

See http://www.ezlan.net/DialUp.html for more info. Don't forget
firewalls, "Internet worm protection," and the like.
