I very much agree with NeoSadist.....that is very HUGE. You need to know
allot about network architecture as well as firewall architecture to make
that kind of decision...not to mention if anyone that actually does answer
that question would damn near type a book to "try" to explain all the ins
and outs of what your asking.

Not to be a smart ass.....( I never flame anyone in newsgroups)....but it
really doesn't sound like you should be doing that kind of work "solo" if
you have to ask a question that insinuates you have little or no knowledge
about architecture/security.

BUT...to quickly answer you...here's the 40,000 foot view;

Firewalls usually touch the internet and protect your DMZ and backend
networks.. which hang off your firewall.
DB servers usually reside in the backend (privately addressed network
segment) of the network and web/apps servers typically reside in the DMZ and
through rules you put in the firewall...these webservers are permitted to
talk through the firewall, to the backend DB servers.

Also...any of what I just said is subject to change based on your current
architecture, security requirements.....there's quite allot involved and
many ways to do it. What I just explained is sort of an industry standard
I've become used to based on 10 years of network and security
consulting.....but again, there is more than 1 way to do this. Good luck to
you though.
