GPL VROC Help on cable modem

my VROC setup to be cable modem, but when I try to join or host GPL only gives me "Connect VIA serial port or modem" and neither of these let me connect. Is there a way to get my cable modem listed as "connect via" option in GPL, so that I can host and join. Thanks in advance, Peter

You need this core.ini in your Gpl directory ; core-server.ini - reduces bandwidth on the SERVER side only. ; ; To use, place this file in the GPL installation folder and rename to core.ini [ Communications ] ; Default send_every is 2. Default send_size is 84. See readme for details. alternate_ip_addr_lookup = 1 net_mdm_client_send_every = 3 ; Client packet freq on dialup net_mdm_client_send_size = 84 ; Client packet size on dialup net_mdm_server_send_every = 3 ; Server packet freq on dialup net_mdm_server_send_size = 84 ; Server packet size on dialup You need the new line alternate_ip_addr_lookup = 1, for GPL to recognize your cable modem !!!!

Thanks, Rejean, that worked like a champ. Peter

See GPL's readme.txt file under the heading "TCP/IP ISSUES". Your cable modem is probably assigned a dynamic IP address. Basically, you need to add the following two lines to a file named core.ini in GPL's home directory. [ Communications ] alternate_ip_addr_lookup = 1 Randy

That doesn't seem to work for my system at the office. We're running DCHP. I can see races and connect just FINE, but I can't *host* races. I used to leave my system in host mode when I left the office, and connect from home. We had some pretty good sessions, including guests Alison Hine and David Kaemmer. :) Anyway, our network was changed to DCHP, and the network admin has been a real *** about letting me keep a static IP address. Is there another work-around? Eldred __ Put your message in a modem, and throw it in the ***-sea... remove SPAM-OFF to reply.

It could be that your dynamically assigned IP address is private to your LAN at work. Or the gateway/firewall may be blocking access to your machine from machines outside your LAN. I know that some have been able to host races from behind a firewall, though I think they've had the opposite problem (they can't join). I don't know exactly what they've done to achieve this. Randy

All DHCP does is allow your gateway machine (firewall) to adapt to a dynamically assigned (by your ISP) IP address. If you're running a server at work (which is behind the firewall), you have to make sure that there are specific ip forwarding rules setup which allows the server to pass UDP packets through on the correct ports. Once that is done, you may have to add this line to the CORE.INI file: [Communications] alternate_ip_addr_lookup=1 For a list of specific IP/packet forwarding rules, go here: http://members.home.net/jms1/gplmultiplayer.html Caveat - this allows me to host races on my side of the firewall, but I cannot join races. Also, if you're not the sysadmin (or are good buds with him/her) for your employer's network, you'll probably play hell getting that individual to change/implement the necessary NAT/masq rules that are required. -- ========================================================= John Simmons - Redneck Techno-Biker (Zerex12) http://www.members.home.net/jms1/index.html John Simmons - Barbarian Diecast Collector http://members.home.net/jsimm/diecast_index.html IGPS Director http://members.home.net/jms1/igps.html If you want to send me email, go to either of the URL's shown above & click "Send Me Mail" in the contents frame. =========================================================

I don't think a firewall is the problem. When I go to host, there is NO option for IP hosting. If I change it back to static, it shows up. Also, the IP addresses are still in the same range as always - 232.50 to 232.250 (example). So, even with the SAME number, it won't work with DCHP... :( Eldred __ Put your message in a modem, and throw it in the ***-sea... remove SPAM-OFF to reply.

The alternate ip suggestion was given to me before, but it didn't work. As far as UDP, I can connect to Battle-net for Starcraft, and create games there. I've been told B-net uses UDP packets. And I never had problems before we went to DCHP. If I change it back, it works fine(meaning not a firewall issue, right?). Any other ideas? That would be fine. I used to set up an unattended race with a LONG practice time. That gave me time to get home and connect from there.<g> Eldred __ Put your message in a modem, and throw it in the ***-sea... remove SPAM-OFF to reply.
