Fine Tuning Kernel Network Paramaters

[Jay <xentekjc_(_at_)_atienza_(_dot_)_dhs_(_dot_)_org>]

This may seem like a very silly question but while playing starcraft from
within a NAT enabled firewall, I keep getting dropped even though im
connected on a cable modem.  I thought maybe the cards on my firewall
sucked.  So i rebooted the firewall into windows and tried playing on
battle.net, and it works fine.  So i was thinking maybe i can tune some
settings.  Is there so docs on tuning these parameters below so that my
NAT enabled computers don't get dropped? Or does anyone have any
suggestions on how I can tune it, I believe the problem is with UDP but I
can't verify that.
