Can you browse the Internet from the squid server itself?

Is it possibly a firewall rule rejecting the traffic from the wireless

Is it possibly a routing rule sending Internet traffic out the wrong

ping for example then do "ip route get" and see which interface it it trying to go out of,
try this with several different internet sites.

Hello, Folks -

I have been using squid/squidGuard on our proxy servers here at the library
work at for about a year and a half, and have been having great success

I am now trying to set up a transparent proxy for a new wireless network so

that we can let folks bring in there laptops and hook up, but have the
content filtered (Unfortunately, that is our policy).

I am using a brand new HP Proliant DL140, with a fresh box-stock install of

redhat 9.0. The server has 2 ethernet interfaces, eth0 is outside, eth1 is

I have tried to set up the machine as described in this article:

I am able to set up squid no sweat, and when I point a wireless client
to port 3128 on the server, squid says that it is fetching pages. When I
point" my browser, I am still able to browse, but squid's access log is

Does anybody have any clues as to where I need to look? Is the above URL a
valid way to do this?

Thanks -
