We use MS EXchange and Active Directory *Cries*. We have Norton 9 Pro on the exchange server which does active scans of workstations throughout the network as well as in coming e-mails. We have recently had the Firewall scan all incoming traffic for certain types of files. We made the scan inclusive for certain common file types example Excell. No excel files of ANY sort get in unless they fit the rules.

When i said "Statics are more important" i am sorry i meant Statistics are more important.

Anyway, so that image is an idea of how it should all be run then? Now to give you an idea of our rack setup... *cries some more*.

To give you an idea of our topology...

we have 1 server rack. with 20 servers (Various sizes) which all plug directly into our Switch stacks.

Our switches hehe. we have 8 patch panels with 24 ports each, these plug directly into the switch stack as well. we have 3 fiber boxes which connect the back (warehouse) to the front, and int he back we have more switches and work stations we are running off of. I can create a visio quick diagram of our server rack and switch/modem stack if that would help with the advice in setup. I will start working on one, it won't take long, and i am sure it would help everyone understand things a bit better.


Question... i am assuming that if OpenBSD 1 fails, signal is still coming from OpenBSD 2, which will allow the network to remain online. Obviously if Hardare firealla fails it all goes down, but nothing we can do about that at presant. And when you say switch 1 and 2 that is just generic names, since they are all on the 2 network right? No matter how we look at it, there is redundat signal coming in PAST the first hardware firewall point. (Looks good, nice and clean).

BTW i like the cloud :-P

NAME
fwb_ipfw - Policy compiler for ipfw SYNOPSIS
fwb_ipfw [-vVx] [-d wdir] [-o output.fw] [-i] -f data_file.xml object_name DESCRIPTION
fwb_ipfw is a firewall policy compiler component of Firewall Builder (see fwbuilder(1)). This compiler generates code for ipfw - a firewall and traffic shaper in FreeBSD (see ipfw(8)). Compiler reads objects definitions and firewall description from the data file specified with "-f" option and generates firewall configuration and activation script. The generated file has a name that starts with the name of the firewall object, with an extension ".fw". It is a shell script that flushes current policy, then loads new filter and nat rules. The data file and the name of the firewall objects must be specified on the command line. Other command line parameters are optional. OPTIONS
-f FILE Specify the name of the data file to be processed. -o output.fw Specify output file name -d wdir Specify working directory. Compiler creates firewall activation script in this directory. If this parameter is missing, then all files will be placed in the current working directory. -v Be verbose: compiler prints diagnostic messages when it works. -V Print version number and quit. -i When this option is present, the last argument on the command line is supposed to be firewall object ID rather than its name -x Generate debugging information while working. This option is intended for debugging only and may produce lots of cryptic messages. NOTES
Support for ipfw was added in version 1.0.10 of Firewall Builder URL
