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? Yr friend in the aether, smogbike

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 -- Arne Martin

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

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. -- **************************** Michael E.

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). Randy
