So you are accessing port 80 at tomcat.no-ip.com? Then you do not reach
squid; you wrote yourself that your squid listens on port 8000. Either
this is not true or the error message is coming from apache, not from
squid. To make sense, your setup needs:

- two IP addresses for squid
- squid listening on port 80 for both addresses
- two ip addresses for the web servers OR different ports (not 80) for
the webservers where they are listening
- squid forwarding rules for the squid addresses and port 80 to the
webserver addresses and ports
- and ACLs for squid that allow the traffic designated for the webservers.

It looks to me you are trying to do it the other way round - putting a
squid on port 8000 before a webserver on port 80.
In this way you will end up with a publicly accessible webserver on port
8000 which is probably not what you want.
Note that there is a fundamental difference between the "normal" and
"reverse" proxy situations; also one squid can handle both you really
need to configure a squid reverse proxy with a public announced port
whereas for an internal proxy can listen on an arbitrary port since the
network is under your control!

Hope this helps,
