Internet server software.

Hi,
I am looking at setting up a neighbourhood isp and have 2 questions

1) If you had every customers computer in the same room, all connected up to
the same wired network, how would you stop each computer being able to talk
to each other. Eg. 192.168.1.1 (server) can talk to everyone and everyone
can talk to 192.168.1.1 but we dont want 192.168.1.2 (jack) talking to
192.168.1.3 (Jill)

I have seen this done before by a local telco and a DSL gaming network where
you would temporarily change your dsl username and password and you got full
speed access to the game network servers, but couldnt talk to / ping / etc
the person you were playing against directly without going through the game
server.


2) Anyone know of a good piece internet connection sharing software that
supports a fair few users - to make it proffessional quality, has qos /
bandwidth limiting, monthly data quotas and a web interface so users can
preferably see their quota usage, has a vpn server so users can vpn directly
to it and not have to authenticate via http, and has upnp etc.
I am trialing kerio winroute firewall but the quotas dont seem to be all
that accurate, and users can start up bit torrent or msn messenger and it
automatically works for them without authenticating, and not going against
their quotas. Where as it seems to start counting when they open ie and
login through the web interface.
Preferably windows based too.

Thanks for your help

Ray;

Don't know if this will 100% address your questions but one or more of the
features may do just that. Take a look at www.netopia.com and look at
their wifi hot-spot software utilities. This software doles out IP's via
dhcp and as it is designed to work in a "public" place I cannot imaging it
would allow cross talk and/or snooping. Might be worth a look.
