GPL 'Net via LAN Problems - Help?

I'm trying to race GPL online from work over the Net and not making it. My machine is connected to our LAN which in turn is connected to the Net over a T1 line. I can successfully ping GPL servers with GPL Net Agent but when I try with GPL it says the following... Opening Channel Opening Network Device Timed Out Opening Communications Channel Closing Network Device Closing Channel I've got a static IP address which GPL seems to see. I tried the default GPL setup then various core.ini tweaks I found on various web pages and always the same result. Anybody have some suggestions? Other than finally buying a state of the art machine for the home? I'm eager to demonstrate my Riccardo Rosset level of GP driving skills... Bill Niemeyer

Have you checked out Alison Hines' Online FAQ? FWIR it covers LANs with a gateway server specifically.

I'm in the same boat that Bill Niemeyer is in (and for the record, the bit on Alison's site does *not* provide a solution). If you're using a router at work, the solution is relatively simple - just use NAT. A friend of mine uses a router on his ISDN line and had to upgrade his firmware to correctly enable NAT, but it works fine now. If you're going thru a gateway box (like me) you have to find a way to do NAT. BTW, Bill never mentioned what OS he's using in his gateway machine (if that in fact is what he's using). A couple of Papy guys are trying to find a resolution and even maybe a software change to make it easier on people like me and Bill. Lastly, I'm using a Linux (kernel 2.0.30) machine as my gateway and am still looking for a kerenel mod or add-on utility that can help make this happen. IP masquerading alone is not enough, or at least not in this version of the kernel. I've seen references to port forwarding being included in newer kernels (ipfwadm) but have't upgraded mine yet to see if it is sufficient. When/if I find anything, I will be sure to a) post it here, and b) let Alison know so she can add it to her online FAQ.

Yes, I have the same setup and am looking at / trying to get ip auto forwarding to work to solve this problem (I am already using masquerading). I'd have thought that auto forwarding all traffic from all ports to my GPL PC would at least work, but it doesn't. Maybe I am using the command (ipautofw) incorrectly. ...Andrew

I think I'm having the same problems too (well - kind of). My configuration is: Ethernet network card connected to ADSL modem for internet access. Second ethernet network card connected to my LAN (so I can share my ADSL with my other computers). This one is configured as 192.168.0.1 --- which is what is listed in GPL's multiplayer setup. I think my problem could be fixed if GPL listed more than one TCP/IP connection. I haven't tried this, but I figure I should be able to play if I remove TCP/IP from my ethernet card which not connected to the ADSL modem. That way I'll have a regular setup. But, it will be such a hassle when I want to race on the net.

I don't have this problem. I have a machine setup pretty much the same way (two NIC's - one going to LAN, one going to modem, and it can host/join just fine. In fact, it's the only way I can join a multiplayer game with my "race" system. I think *your* problem is more a configuration problem under windows. says...

Oops... I got it working. I didn't read the readme.txt part about core.ini thing which can be used for setups like mine. >I think I'm having the same problems too (well - kind of). My configuration

GPL will list as many IP addresses as it can find (well, ok, up to 6). By default GPL will look in the registry for static IP addresses, and then use DUN (if it's installed) to find dialup networking addresses. This method will miss any dynamic IP addresses assigned via DHCP. If you use the alternate IP address lookup (see the readme.txt), GPL will use gethostname() and gethostbyname(), and then DUN, to find IP addresses. This alternate method is more comprehensive, but can cause you grief if you have "connect to the Internet as needed" enabled, and aren't connected when you start GPL (which is why we don't use it by default).
