Re: [PLUG] dual networking question

[David Coulson <david@davidcoulson.net>]

In general, yes, you can have two inside networks/VLANs utilizing a 
single internet connection. That said, most linksys routers (at least 
the home/smb ones) don't support VLANs on the ports and don't let you 
configure multiple subnets.

Hacky way of doing it would be to plug one linksys into the internet 
directly, which would be your 'public' network, then plug another 
linksys into the back of that (using the second linksys' internet port), 
although you end up with double NAT which might break a few things.

I know you can easily do this with Cisco ASA firewalls, but not sure 
about low-end stuff - Netgear have some firewall/routers which support 
VLANs/subnets/etc, plus you can actually have multiple wireless SSIDs on 
a single device which drop users on different VLANs so you don't have to 
mess around with non-overlapping channels and stuff. FVS318N is a 
netgear product I know works - got one here (although I don't use it much).

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 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.
