Hi, >
It is more of business-related decision. If you have sensitive business related information stored within your network, you definitely need a good firewall irrespective of size of your network. For example, Checkpoint, Netscreen, etc. >
However, firewall is always a must. If not a dedicated one, atleast tightly written ACL on the gateway router. >
>
You may think of having a LINUX box running iptables. Low end PIX if fine as well. >

Hope this helps. >
Best of Luck, >
