[squid-users] Chaining of proxies

Hello,

I'm new to this list but have searched the archive for my following
problem. My setup is as follows:

I set up a squid as proxy cache for our department which is connected over
a slow line to the main firewall of our institute.

  [local-1]
            \
  [local-2] - [squid-cache] --(slow line)--> [firewall of institute]
            /
  [local-3]

Now the situation has changed and we have to use a proxy instead of the
"firewall of institute". I just get 403 errors with my current (mostly
standard) squid setup or even if I try to connect directly to the
internet from my workstation. I'm using squid 2.2.5 from Debian 2.2.

The list archive mentioned the cache_peer option which should be
my friend to solve this problem, but I suspect I did not use the
right options. I tried

cache_peer wittenau.ivbb.bund.de parent 80 7 no-query
and
cache_peer wittenau.ivbb.bund.de parent 80 3130 no-query

but I've got in both cases:

                                   Error 500

   Reason: Can't locate remote host.

I really don't know anything about the proxy
which is used and I hope that no-query was the right option to tell
squid that it doesn't try to obtain something from the cache. I don't
understand the ICP concept but I'm afraid that the used proxy isn't
as clever as squid might be.

Any idea how I can chain the proxies right?

Kind regards
