Looking for small firewall device for isolating hosts on LAN

Hi all,

I'm looking for a cost-effective firewall/router/switch solution to enable us to isolate specific LAN hosts or small subnets from the rest of our LAN. The idea being to provide third-parties access to those hosts but prevent them from potentially attacking other hosts on our network.

We already have a solution for providing the remote access but just need to isolate the hosts/small subnets.

The ideal device would have 4 or 5 ethernet ports and allow us to set fairly simple rules between hosts on those ports and our LAN, along the lines of...

From : Secure Access Device     To: Isolated Servers           Service : PCAnywhere ? MS Terminal ? Citrix ? HTTP ?
From : Isolated Server - Port 1   To: LAN                            Service : FTP
From : Isolated Server - Port 2   To: LAN                            Service: SMTP

Additionally the device might do some simple static routing.

There are plenty device out there that can do this but they also tend to do a lot more besides so the cost can often become quite prohibitive. The above is all we really need this box to do. We were hoping to find something in the £400/$750 range. Equally we also prefer to avoid buying small SOHO type devices for every single host/subnet we want to isolate.

Is there such a box out there? Any help would be greatly appreciated.

TIA.

Try Sonic Wall TZ170, it is setup to accept more than one subnet and gives you all the control you need. I've got a couple of networks I maintain setup with these.

Netgear FVS318  The best device to do what you need...

Or you could use open source.

All you need is the hardware.

Thanks for your responses guys.

Jeb911: Have you used these NetGear products for a similar scenario? It does look like these firewalls would achieve our basic objectives but is there any control over traffic between the LAN ports? Ideally we'd like to set rules there or at the very least isolate each LAN port so that devices on the LAN ports can communicate with each other.

Nexissteve: We had thought about the open source route but would prefer not to go down that road at this point.
