First thing is to narrow down whether the problem is happening on your
LAN, between you and your ISP, or out on the net at large.
The first step in the process is to see whether you are reaching a running
squid. Telnet to port 3128 from one of the client boxes, and feed it a
request like: 
GET http://slashdot.org/ HTTP 1.0 <ENTER><ENTER>
If anything at all comes back, then your LAN is not the problem.

So if you can make requests of squid, the question is why squid is unable
to respond to them. Try to make a web connection from the server to
somewhere out in the wild blue yonder, to determine whether it is possible
for squid to answer requests.

I'm more conversant with Debian, but it really does seem this is a generic
problem.

No need for IP forwarding to run squid. Without masquerading, 
IP-forwarding wouldn't get you anywhere, anyway.
cat /proc/sys/net/ipv4/ip_forwarding.
1 means it's enabled, 0 disabled.

No it shouldn't. Launching squid without -D will cause it not to start if
it can't find the DNS, but you give me the impression that you know it is
running?

Yeah, that might be me. don't seem to have any plans.
Wherebouts are you? It might be easier if I dropped in or something.
