Firewall Wizards: Re: Palo Alto Networks

[Paul Hutchings <paul () spamcop net>]

Thanks all.

Frank, We would only be looking at one unit so management shouldn't  
be an issue.  You mentioned "home grown apps" and giving them a  
definition, this will hopefully all be clear once I have a units GUI  
in front of me, but presumably if you need/want it to the PA boxes  
can also act as dumb stateful firewalls i.e. "Simply allow port XYZ  
from X to Y"?
Arkanoid, I've learned not to trust the marketing hence lurking on  
technical forums and lists like this.  Also (again may become clear  
when in front of one) but how does the SSL inspection/MITM actually  
work i.e. what would I need to change on my clients and could it also  
be used to apply inspection to inbound SSL traffic to look for  
nasties i.e. Outlook Web Access?
As a general question, what strategies are people taking these days  
regards "layering" firewalls?  We currently use a back to back  
approach with a dumb stateful firewall at our perimeter almost as a  
"doorman" so that only the ports we need to allow in get in, and then  
we get a little smarter i.e. does it conform to RFCs etc. at the LAN  
edge firewall.  I'm wondering if the general consensus is that this  
is still a sensible idea?
