Cable Modem -ISP operated firewall?

Hi, Is my ISP (cable modem) operating a firewall on our behalf (I hope not!) I'm trying to host GPL Internet racing. I can join races but I cannot host them. I'v totally disabled ZoneAlarm security software (and rebooted) . I've checked my ports and shields Using 'Shields Up!' Shield Up! reports: Shields - Your Internet port 139 does not appear to exist! Unable to connect with NetBIOS to your computer. Port Service Status Security Implications - 21 FTP Closed 23 Telnet Closed 25 SMTP Closed 79 Finger Closed 80 HTTP Closed 110 POP3 Closed 113 IDENT Closed 139 NetBIOS Stealth! IMAP Closed 443 HTTPS Closed Can anyone tell me what's going on and is there anything I can do about it. Interestingly, if I logon to my ISP through dialup modem I can host races. Obviously this is hopeless for serious racing. Thanks Alan

I don't think you have a firewall problem. Do you have the following entries in your core.ini file? [ Communications ] alternate_ip_addr_lookup = 1 If not, that is your problem. Regards, Gordon "Alan Coates" <[email hidden]> wrote in message news:GOzS5.1382$[email hidden]...

I've got some steps to track down the problem: 1. Connect to a VROC racelist, http://www.vroc.net 2. Ask someone to ping your IP by opening a MS-DOS box and typing "ping xxx.xxx.xxx.xxx" to verify you are being seen. 3. Try non-dedicated hosting first using the VROC host menu option. 4. Turn off the "skip connection screen" option. This will allow you to verify the connect which GPL is using. 5. When GPL starts, make sure you select the the TCP/IP port to accept connections on. This would be the same port in which you use to join races. If you don't see your internet TCP/IP port as an option, add the core.ini entry noted by Gordon: [ Communications ] alternate_ip_addr_lookup = 1 That should help you get started on tracking this down.

My ISP: Telstra Bigpond Cable Australia closed port 139 a few weeks ago to stop the spread of some trojan? virus. Are you with Bigpond? If not... perhaps some other ISPs have been forced to do the same? Mark Lee "Alan Coates" <[email hidden]> wrote in message news:GOzS5.1382$[email hidden]...
