DSL Modem/Router and Internet Connection Sharing

[keving98]

Don't know if this is possible…

I have a customer with DSL using a 2wire 1801G wireless router. There
are (6) desktops with (1) acting as a server (XP Server) for some
custom software for their business. All desktops are running XP
professional. I'm trying to make the network as fast as possible for
this custom software so I got a gigabit switch and all the desktops
have gigabit ethernet cards. In the interest of keeping the 2wire out
of the gigabit loop I set up Internet Connection Sharing on a second
(10/100) ethernet card on the XP Server. The 2wire router is set up
in the default router configuration doing the PPOE login. The router
assigns IP's in the 192.168.1.x range to the (4) switched ports and to
the wireless clients. The WAN port on the XP Server is manually
configured to 192.168.1.65. The LAN port on the XP Server is manually
configured to 192.168.0.1 by Internet Connection Sharing. All the
other desktops are assigned IP's by the XP Server and are working fine
including internet access. The problem (not surprisingly) is that
when wireless clients connect to the 2wire box they are assigned IP's
in the 192.168.1.x range and are on the other side of the XP Server's
WAN port.

So... Is there a way to allow the wireless clients through the XP
Server's WAN port to connect to the network? Forgive my ignorance but
isn't there a way to tell the XP Server and/or the 2wire box to allow
communication between the 192.168.1.x and 192.168.0.x networks?

Any help would be greatly appreciated.

I think that this setup is unnecessarily complicated. I'd connect
everything, including the 2wire, to the gigabit switch. I don't think
that would have any negative effect on network traffic between the
computers.

To make the router+ICS setup work, you'd have to:

1. Assign static IP addresses to all of the wired and wireless
computers.

2. Create an LMHOSTS file on each computer to specify the mapping of
computer names to IP addresses for the computers on the other network.

3. Enable routing on the XP server to move NetBIOS traffic between the
networks.

4. Use something other than My Network Places to access computers on
the other network.

I took your advice and connected everything, including the 2wire, to
the gigabit switch.

Thanks for your help.
