Network Configuration

I need someone to configure a \'dual-firewall dmz\' utilising an existing router (as the perimeter firewall) and a new SonicWall firewall. It will need to be set up so that the web server \'lives\' in the DMZ, with everything else behind the second firewall, which will also need to receive VPN connections. The web server will need to \'talk\' to a database server that will reside inside the \'internal\' network.

The work will need to be carried out on site in the Nottingham area, in the next week to 10 days.

We may need ongoing support or training to maintain / update this configuration in the future.
The servers on the network are all Mac (OSX Server), so my preference would be for someone who has Mac experience, but this is not essential.
