How to join GPL online races?

If iGOR doesn`t show a racelist:

The Bandwidth-Patch is needed to join most of the GPL servers.
Infos & download of the Bandwidth-Patch here.

These entries should be set in your GPL core.ini (X:\...\Sierra\gpl\core.ini):

How to adjust the chat (& replay) font?

Who is running GPL with a high resolutioin (1024x768, 1280x1024, 1600x1200) might have difficulties to read chat messages at online races as the font gets too small.
This patch allows you to increase the font size to make reading easier.
The replay font gets also increased.

How to host online races with iGOR?

GPL/ iGOR Ports and Firewalls

General Listings of the ports
Port 113 (TCP/incoming) - not essential
Port 6970 (UDP/outgoing)
Port 6971 (UDP/incoming)
Port 6667 (TCP/outgoing)
Port 30196 (TCP/incoming)
Port 30196 (TCP/outgoing)
Port 30197 (TCP/outgoing)
Port 30198 (TCP/incoming)
Port 30198 (TCP/outgoing)
Port 30199 (UDP/outgoing)
Ports 32766-32786 (UDP/incoming)

iGOR Ports

iGOR uses several ports for internet communications. Some of these can be changed, others cannot.

IRC Chat
Port 6667 (TCP/outgoing) - cannot be changed.

IRC Ident Server
Port 113 (TCP/incoming) - cannot be changed.
- it is not essential that this port is opened, but chat connections will be much quicker if you can open this port for incoming connections / add it to your port forwarding list.

Race List
Port 30197 (TCP/outgoing) - cannot be changed.

Remote Hosting Client
Port 30196 (TCP/outgoing)

GPL Ports

By default, GPL uses the following ports:

Port 6970 (UDP/outgoing) - used by GPL to broadcast the status of the races to the RaceList server.
HOWEVER, iGOR changes this port to 30199 (UDP/outgoing) to keep the range of ports required by iGOR to a single block (30196-30199).

Port 6971 (UDP/incoming) - used by GPL for ping responses. Not used by iGOR

Racing Connections

Ports 32766-32786 -- 21 in total (UDP/incoming)
Details: 32766 is used for incoming connections, 32767-32786 are used for existing connections to each individual client
