Firewall suggestions please...

[Douger9999]

Hi all,

I have the need for a firewall with some fairly precise requirements, I was hoping for some advice please.

Firstly there are 4 Zones of trust needed within the system.

WAN
Trusted, full access to all zones
Trusted, partial access to WAN and Trusted
Trusted, no access to any other zone


Firstly there is the WAN, I want to block all inbound connections from the WAN. This zone could include a) pc's on other networks b) the internet.

Secondly there is the trusted zone. Within this zone, I wish to allow connections to all other zones.

The third zone is comprised of a PC which needs access to one of the trusted PC's on a TCP port and access to the WAN on ports 80, 21 etc.

The last zone need allow no outward connections, or inward connections except from those specified explicitly above.

Can anyone suggest further reading into the subject for me please and the possible make and model of a hardware firewall which would suit my needs.

Many thanks

Doug

Hello -

You might want to check out the SonicWALL NSA 240 (http://www.firewalls.com/sonicwall/sonicwall-firewall/sonicwall-nsa-series/sonicwall-nsa-240). The NSA 240 will allow you complete control over as many zones as you like.

Once you establish your zones you can build firewall rules / policies for each zone and create all the trusts you need to accomplish what you are looking to do.

Hope that helps.
