If I'm in the wrong group, or if there is a group better suited to
addressing this question, please let me know and I will repost there.

We have a small business (art school for kids) and we want to allow
customers to use our internet access as a perk when they are waiting. I
am somewhat network savvy, so I understand the basic concepts of
routing, switching, firewalls, etc., but I'm not so savvy that I know
the available equipment and intricacies of each. IOW, I'm not exactly a
n00b, but then I'm not an expert either otherwise I wouldn't be
asking.....

We just got DSL at our business. We have a Siemens DSL modem that is
currently hard-wired to our computer. I'd like to be able to connect
one or two more computers to this computer and the internet, and these
can either be wired or wireless. Additionally I'd like to be able to
provide a wireless access point for our customers separate from the
business network.

If I understand my requirements correctly, what I think I need is a
small router that can separate the two networks, and wireless switch
for the customer access point. What I don't know is if a wireless
router can do both jobs.

My home network is a wireless router (2Wire 1000HW) that is fairly well
locked down. I use a 128 bit WEP and I don't broadcast the network name
to keep casual attackers out. The advanced settings allow for public
access to the network from the internet (disabled), a bridge network to
allow broadband IP addresses to be used on the local network (also
disabled, but not sure what this means), and a private network with
DHCP addresses.

A pointer in the right direction would be greatly appreciated.

Purchase a D-Link DFL-700 Router, it has two network jacks (well 3 if
you count the WAN), one for LAN (your internal network) and DMZ for
external/isolated connections.

If you setup the AP in the DMZ then guests to your network won't be able
to access your local LAN computers/network, but they will be able to
access the internet.

If you use any other method, where they are not isolated networks, you
run a BIG risk that someone accessing the AP will compromise your
network.

Where's the lock?

Yeah, sure. Even scriptkiddies know how to use NetStumbler and AirCrack.

WPAv2, IEEE 802.11i, IPsec, VPN

Hi,

First of all, i'd advice you to add a switch with VLAN capability to
totally isolate your business network from your public network. I mean
this is the right way to do it . you can find some enterprise level
access points that support VLANs over wireless, and i would also advice
you to go for WPA-PSK at least ;with a really random pass-key. WEP is
crackable in 5-10 mins max, even if you shutdown SSID broadcast.

cheers
