Shorewall users - Dec 2004 - [slightly OT] Calculating subnets

My home lan is 192.168.174.240/29 so that I have 192.168.174.240 as net, 
192.168.174.247 as broadcast and space for 6 hosts (have 2 PC and one 
router).

Now I would like to edit the rfc1918 file in order to exclude this range 
from the list.

What is the way to compute the most compact notation to say that only 
192.168.0.0-192.168.174.239 and 192.168.174.248-192.168.255.255 are to 
be discarded ?

TIA,
Bob
