Setting Up Wireless Access In A Cafe while protecting my n..

Archived from groups: alt.internet.wireless (More info?)

Hello,

I have a small cafe with an office in the back. We have a linksys
wireless router. Currently, all of the computers in the office and
cafe are accessing the internet and each other through the router -
small network.

I would like to offer free wireless service in the cafe to my
customers through my existing service. The problem is that I don't
want them to be able to access my network. Is there an easy way to
setup a second access point that taps into the primary router, but
only allows the connection to get to the internet?

Thank you very much
Mal

I posted some methods in the distant past. See:

Not a 2nd "access point" but perhaps a 2nd "wireless router". The
easiest and most expensive way is to arrange for a 2nd IP address
from your ISP. Both IP's go through the DSL or cable modem, which
then goes to a cheapo 4 port ethernet switch. From there, they go to
your two routers. Neither LAN on each router can see the other.

If two IP's are deemed excessive, then put the two routers in series.
Something like:


/----\ /----\
== DSL ====| |======================| |====
Modem | |=== 192.168.0.xxx | |==== 10.0.0.xxx
| |=== | |====
| |=== Office LAN | |==== Coffee Shop
| | | | Network
\----/ \----/
Router #1 Router #2
Wireless 192.168.0.xxx Wireless 10.0.0.xxx
for office LAN for coffee shop

I'm not really sure which network should be the coffee shop and which
the office LAN. Probably the way I drew it because it's fairly easy
to monitor and sniff the coffee shop network at the office LAN router.

Like as been said before get a second wireless router, B wireless routers
are cheap, get a cross over cable plug the new router in to the old. Give
the new router a different SSID and channel number and different IP number
and enable auto DHCP, no WEP or WPA. On your existing router enable MAC
filtering. and WEP or WPA.

It would go into the router, but right back out to the appropriate IP,
methinks.

There-ya-go. Winner. Oops, there's a caveat in bold:
"The ZoneCD can be configured to block all network traffic to your *wired*
network. "

Of course, that's also a good reference page for the Original Poster.

Thank you very much for the help. I really appreciate your time and
effort. I will be in the cafe next week and will give it a try.
