[Samba] Packet filter rules for "outgoing" SMB connections/mounts only?

[Alan Becker]

Try the firewall script at:  http://projectfiles.com/firewall.  I have 
used this script
on RH 7.x, 8 and 9 boxes.  It is very simple to use for simple 
applications, and
yet has considerable power for more challenging situations.  It requires 
iptables
in order to operate.   The "graphical" installer actually uses 'dialog', 
and has a
text-based menu interface.

If I understand your request correctly, it would be handled that way by 
default. 
Once the firewall is started, any external connection that is not 
explicitly allowed
will be denied.
HTH,
A. Becker
