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
