I need to build a firewall as soon as posible. But, I've got a big =
problem...
   In my company, we have 32 IP addresses (actually is only 29) in =
network and one cisco router to pass through our internet traffic.
   I plan to put a unix system's firewall in my local network to protect =
my several servers. But I don't know how to configuire my network. =
Should i need to make subnet for my IP addresses or i can use same IP =
range IP address for both devices on my firewall....
The skeme is below:
-------------         -------------         ----------------------
| Router | ------ | Firewall | -------| Local Network|
-------------        --------------         ----------------------
                                                                       =
