Kirk, 

        Can it YES !!  Will it depends on you. The most important step in 
choosing a firewall is to first define the security policy your 
organization is going to operate under, then look at the features and 
functions available in the Firewall product and see if there is a match. 

        Also, be sure you understand, the traffic flow requirments, and 
the address implications.  Version x.y (Not sure what the AS/400 product
was released at) does not support Network Address Translation. Therefore 
if your existing network must have external IP addresses, using the 
AS/400 product means new/additional definitions, route tables, etc. 
internally.

        Where are you "public" servers, on the secure or unsecure LANs. 
What access do unsecure servers need to secure servers and data.  What 
protocols are used to access this information ??  

        Other issues in your policy may drive other questions, but I hope 
you get the basic idea.  If you have deatil questions please feel free to 
post them or use my direct E-Mail address..
