IV. MULTIPLAYER ISSUES
----------------------

MULTIPLAYER BEHIND A FIREWALL OR ROUTER

By default the following UDP ports will be used by NASCAR? Racing 4: 32766
for the net_server_port, 32767 for ping port, and then sequentially numbered
ports for each allowed client connection (max of 42) starting at 32768.

To run from a machine with a private IP address behind a Linux firewall, you
need to use a combination of IP masquerading and IP autoforwarding.  The
following rules for the default 42 client port range can be used:

 ipfwadm -F -a accept -m -S a.a.a.a/m.m.m.m -D 0.0.0.0/0
 ipautofw -A -r udp 32766 32809 -h a.a.a.a -v -u

Where a.a.a.a is the address of the machine behind the firewall, and m.m.m.m
is the netmask.  If you run a server behind the firewall, clients should
connect to the IP address of the firewall.

Note that users with Linksys or other such Internet connection sharing
routers should not need to change any configuration settings to connect to
NASCAR? Racing 4 multiplayer races as clients.  If you wish to host a
NASCAR? Racing 4 race from behind a router you will need to forward the
default UDP port range of 32766-32809 from the router to the internal or LAN
IP of the NASCAR? Racing 4 server.  Linksys users will need to latest
firmware update to allow port ranges to the forwarded.  When connecting,
clients should use the external or WAN IP address of the router.

I set up packet filters to allow udp ports 32766 and 32767 but it still
won't work any ideas how to configure.
