4.8-Stable DummyNet

[bigtruck at ownij.com]

Hi.  We just opened a gaming center and have chosen to run a FreeBsd box for 
our firewall.  IPFW is configured at it's very basic running natd through rl0 
and allowing any to any connections from the lan to the outer world.  Natd 
controls access to the lan.

We have a 6.0 mb/s ADSL net connection for all the gaming clients to use, 
however if a gamer starts downloading a file, that file takes precendence and 
causes everyone's pings 'in-game' to sky rocket to unplayable levels.  I have 
done some reading on DummyNet which is attached at the hip with IPFW, however I 
have been unsuccessful in getting it to work properly.

I have done some research and found this site: 
http://info.iet.unipi.it/~luigi/ip_dummynet/

After reading I became more confused than before.  Should I share the link as a 
whole to all 64 client machines OR should I set a fixed BW for all client 
machines.  Are there other websites out there that can help with this?

Also if and when I do find a working pipe/queue config do I put it before the 
natd via rl0 command or after?

Thanks.
