Hi all,

Well, How about setting your wireless in a complete DMZ off the Firewall,
and only HTTP traffic can flow out to the internet and nothing else.
      Plus (This is a maybee) could setup and user ID and password @ the
firewall so, any client that connects to it needs to authenticate to the FW
before is allow out ... this will help knowing how legit and who the user
is ...
      Plus change the password on this FW user regularly and do not publish
it or give it away untill needed.

As an example, what happens if a person (unknowingly) connects wirelessly
and downloads a music file? They are outside our firewall but they are
still connected to our network. Wouldn't the company still be liable?

Thanks.

Robert

I'd put the access point outside the firewall if you have the public DHCP
address space. If not I'd put it on an isolated DMZ segment. SSID of
"meetingroom" or "visitor" with WEP disabled. That gives them the Internet
with no more rights than any other outsider.
