RE: [OT] what firewall for allowing only one port open on a connection?

Hi Neil,

Isn't there some system already in the building that protects the users
from each other. You will need to open a hole in that system first anyway
so wouldn't that do for you anyway.


Regards,

Paul

The scenario

In a multi tenanted building, I need one of the tenants PCs to have
access to the BMS supervisor.

The BMS supervisor is sitting on the Landlords network so the Landlord
is a bit worried that the tenant will start snooping around the rest of
his network..

The application on the tenants PC uses just one port to access the
Landlords BMS PC (Port 10051) So, I need a firewall to sit between the
tenants PC and the Landlords network that only allows that single port
to pass through the firewall.

I've purchased and configured a few Broadband routers etc but I have no
experience of this sort of application.

I've seen a few firewalls in the Misco catalogue but they seem to major
on VPN's etc and seem to indicate that the WAN side can only connect to
a broadband router.

So, that's the scenario (hope it makes sense). The question is, which
firewall should we get. It needs to be cheap(ish) and not PC based. I've
seen a netgear FVL328 - would that work?
