Firewall Planning/Design

[genghiskhan]

I am in the planning/design stage of implementing an upgrade to a PIX 515e. The PIX currently has 3 intfs (inside, outside, notused).

We are upgrading to a total of 6 intfs soon. Most likely using only 5 of the 6 intfs with 3 as dmz's due to location and adminstrators of servers connected to them.

I am looking for any documentation pertaining to planning/design of a firewall. What should be considered for connectivity and security?

Any help is appreciated!

Thanks!

Your question is too generic, Best would be to search on CCO and Google for design guides, basically if you can design your network for a pix with two interfaces then you can design a PIX for 6 interfaces, there is nothing different.
