FreeBSD 5.1 <-> WinXP Networking Problem UPDATE #2

[freebsder]

OK - I have taken everyone's advice and made some
changes to my  rc.conf.  Things have improved ...

All my computers can ping each other!  BUT I can only
connect to the internet from the FreeBSD server.  All
requests made by the WinXP machines go unanswered!! 
Yet when I ping from them, they can connect to any
computer on the network BUT CANNOT ping OUTSIDE the
network nor fetch any information outside this
network.  

Any ideas why my FreeBSD machine is not routing these
requests and putting up a road block?
