[squid-users] Squid will not forward to peer

Hi All,

We have implemented a squid server on Opensuse 10.2 to cache some of our
web traffic.

We have a peer proxy server which is externally managed and filters
malicious traffic, its address is xxx.yyy.zzz.27 and listens on port
8080 for requests, this is working fine from the xxx.yyy.zzz.0 network,
we have now implemented a squid cache on ip xxx.yyy.zzz.34 which fetches
pages from the internet and caches them locally, this also works fine.

However, we would like to have xxx.yyy.zzz.34 fetch its pages from
xxx.yyy.zzz.27 on port 8080 which will then retreive them from the
internet and pass back to xxx.yyy.zzz.34.

I have tried adding the lines,

cache_peer iwss parent 8080 8080 no-query default
acl all src 0.0.0.0/0.0.0.0
never_direct allow all

To the config file which (I think) should work, Ive also cleared the
cache to force it to download the new content via the other proxy.

When connecting I get the error message,

########################################################################
While trying to retrieve the URL: http://www.google.co.uk/

The following error was encountered:

Unable to forward this request at this time.
This request could not be forwarded to the origin server or to any
parent caches. The most likely cause for this error is that:

The cache administrator does not allow this cache to make direct
connections to origin servers, and All configured parent caches are
currently unreachable.
########################################################################

Ive noticed that when using firefox from the proxy (Linux squid) box,
Ive mapped the name iwss using hosts file in linux to the xxx.yyy.zzz.27
server and if I config firefox to use xxx.yyy.zzz.27 8080 in proxy
settings it connects via the proxy fine, if I config firefox to use iwss
8080 then I get a cant connect error message

Ive also tried to specify the other proxy in squid.conf by ip address
aswell but this also fails.

Any help on this would be much appreciated, Im tearing my hair out. I
honestly have tried in my limited knowledge.

Thanks much in advance

Mike W
