Just upgraded entire home network to W98SE, and gained the easy
networking wizard known as "Internet Connection Sharing" ... works
great, all 3 PC's now share the DSL line, BUT ... I've lost the ability
to host and/or join multiplayer races on my LAN ... it's driving me
nuts!

Any ideas and/or commiserations?

This is because ICS basically sets up a firewall, closing all ports for
incoming connections. To open the ports again go to:
http://www.timhiggins.com/ppd/icsconfiguration.htm
and download the program to configure your ICS setup. For GPL you will
have to open a range of UDP ports for incoming connections:
6968-6971
32000
32766-32786

  Ok Arne, where do I run this program?  on the host machine or
on the client?  Thanks...

You should run it on the machine which is connected to the internet, as
that's the one which has the firewall. I also think you will have to use
this machine as the host.

With the ICSconfig program, you can specifiy which IP address (i.e.,
machine), will be the "host".  You can only have one machine receiving
on the ports needed for GPL online racing.  I have it set up so I can
disable one machine in ICSconfig and enable another.  That way I can use
a dedicated host for league hosting and my main machine for general
hosting.

Before you installed ICS, you were probably using static IP addresses (e.g.
192.168.0.1) for each of the machines on your LAN.  But to use ICS, the
'clients' of the ICS server need to use dynamic IP addresses.  GPL's default
method of finding IP addresses on a machine will only find static addresses
(and dialup networking IP addresses).  Add the following two lines to your
core.ini file to tell GPL to use its alternate method of finding your
machine's IP addresses.  That will more than likely solve your problem.

[ Communications ]
alternate_ip_addr_lookup = 1

Also, if you run a GPL server on your LAN, and connect to it from another
computer that is also on your LAN, you might want to consider adding the IPX
protocol to your LAN (standard disclaimers re: your network going haywire
trying to do this :-).  A GPL server will send more information to clients
that are connected to it using the IPX protocol (on the assumption that it
will be a LAN connection, and not, possibly, a dialup connection).
