Problems when trying to host races behind a router

Two weeks ago I had a cable modem installed and have been able to host GPL
and N4 races on my main racing PC whilst running Zone Alarm 2.6.231 by
setting the ZA internet security level to Medium and the GPL and N4 programs
set to allow server connections in ZA.

Today I bought a Netgear RP114 cable router/switch with the intention of
running a 2 PC LAN with one PC acting as a race server and a second PC (my
main race box) joining the server via the LAN.  Initially I want to get a
single PC configuration set up using my race box (mainly because I need to
get my second PC back from my sister who I leant it to).  Unfortunately I
have been having some problems.

I am able to see the net, send e-mail and most importantly join GPL races
via WinVROC through my new setup with my PC hooked into the router and the
router hooked up to the cable modem whilst running Zone Alarm.   What I
can't do is host a GPL race.

The router is set up to get it's IP from my cable company's DHCP server
which it does successfully.  The router also acts as a DHCP server for the
LAN and dynamically allocates IP addresses to the LAN in the order in which
the PC's are booted up.  The LAN IP address of the router is 192.168.0.1 and
my race box so far has always been 192.168.0.2.

I looked at Alsion Hine's information on setting up a server behind a
router.  From the information there I gathered that I needed to open a range
of ports on the router.  I logged on to the router configuration menu, went
to the Advanced - Port Forwarding menu and set ports 32766 - 32786 and
6969 - 6971 to be forwarded to IP 192.168.0.2 (my PC).  When people tried to
join the server they got a timed out message.  I then tried the same setup
with ZA switched off completely but it didn't make any difference.

Obviously I am missing something so am looking for suggestions on what I
should do to get this setup working.  Has anyone else been able to host from
behind a Netgear router?  Any help is appreciated.

Cheers

I had much the same problem. Have a look at your server.ini file in your GPL
directory and see which IP is listed under   [ip0] and [ip1]. The one you
want to host from should be listed under [ip0] , if not then just swap the
ip addresses around for [ip0] and [ip1]. You will find that you will have to
swap these everytime you start vroc and want to host. I just made a copy of
the server.ini after i swapped the ips , into a different directory and copy
it back when hosting. Don't know how to my main computers ip to stay at
[ip0].
Hope it works for you :)

Did you open the ports for the UDP protocol? That's what GPL uses. TCP ports
need not be opened.

Thanks for taking the time to reply.  I have got things sorted out.  It
turns out I needed to set a static IP address for my PC despite it being the
only one on the network at the moment.  I couldn't get this working last
night but managed to sort it today.

Also I needed to increase the port numbers open by one either way.
According to Netgear the ports open do not include the port number you enter
in their configuration manager so I had to enter ports 6968-6972 and 32765
to 32787 to allow GPL to host.

Now all I need to do is get my second PC back from my sister to act as a
server.
