Setting up a DMZ

[The_KiD]

Guys I need some advice on how best to set up a DMZ for a web server.

We have a webserver that needs to be accessible from the internet and at the same time has a connection to our DB server.

The firewall has a spare port on it, but I am unsure how to go about the basic setup of a DMZ.

Any advice you can give is appreciated!

Thanks

It is professional kit, a Cisco PIX firewall.

However I not so much after the configuration, but more an overview of how it would work.

Networking and security are not my strongest points.

Am I being ripped off?

ok a little advice needed here.

Basically we have a managed firewall from a company.

Our internet connection comes in VIA their data centre, then down a 10Mb leased line to us.

I need this DMZ created on the managed firewall and they are saying that it is 2 days work and chargeable at £1100/day

Can anyone who works for a networking or managed services company tell me if I am crazy in thinking this is extortionate for what I imagine to be some rule changes based on the PIX firewall.

We have 5 spare one's on that connection.

We also already pay this company close £4K/month for services with them.
