[NCLUG] smoothwall questions

[rosing at peakfive.com]

I got smoothwall.  It works great (other than the fact that I couldn't
figure out how to add a driver for a card it didn't know about). But
I'm curious about one thing.  In the documentation it says:

  Also note: Ports above 1024 are allowed through automatically. For this
  reason, it is not recommended that you forward these ports if you require
  restricted access by source IP address.

What is this saying?  It lets everything above port 1024 through but
it doesn't forward them?  I'm confused.  After being told the ills of
letting X requests through I want to make sure it doesn't happen here.

Thanks,

Matt
