Re: [PLUG] dual networking question

Hash: SHA1

Rather than reply to each email let me just say "Thank You All" for the great information and dialog!

I met with the consultant and we're in agreement that there needs to be two Comcast Internet connections! The second is not for the guest network but for the school that operates in our building.  They must have, by law, filtered network access.  Since we don't wish to utilize the filtered connection we'll just get our own.

He's going to recommend we install three wireless routers that provide a separate 'guest' access.  That guest can only access the gateway and can't even ping an adjacent ip address on the network.  I'm going to press for the ip range to be expanded because while 255 addresses seems like enough today I have serious doubts about future growth.

Thanks again.

One will be staff only and will have access to the network resources (printer, shared drives, etc. as well as the Internet.)  The other will be public access and only have access to the Internet.  The consultant has said that we'll need a second connection to the Internet (currently we have Comcast.)
> I think he's wrong.  I think we can have two separate networks with different ip address ranges and the server (Windows Server 2008) will only allow one of those ranges to have access to the network resources.  Everybody would have access to the Internet.  My idea is that the staff network would be 192.168.1.x and the public network would be 192.168.100.x.  The staff wireless network would be the same ip range as the Ethernet network in the office.
