Re: AS400 connectivity VIA the WEB....

I know there are many AS/400 machines outside a firewall.  Have any of 
those had troubles yet that would have been prevented if a firewall had 
been there? 

So far the only useful business benefit I have seen from the firewalls has 
been to keep employees from reaching the internet with telnet and Instant 
Messenger types of activity but on the other hand I have seen performance 
degrade and connectivity issues arise from these firewall schemes.  It is 
raising the question in my mind of the value of the inbound firewall.

just because you can ping out does not mean that your as/400 is outside
the firewall.  you most likely have an internal addressing scheme and
the router does all the communication to/from the outside.
