Mojn, mojn :-) The problem is here: .... http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost manager http_access deny manager http_access allow localhost http_access deny all #<-------------------------- You only allow access to your squid from "localhost". So http_access allow all would fix it. NOTE: I do not see any connection to DG in your config ... Most likely, DG should be upstream proxy to squid, so the chain of proxies might be like this: client ---- squid(transparent) ----DG ----web Then you need something like cache_peer 127.0.0.1 parent DG-port 0 no-query no-digest no-netdb-exchange in your squid.conf -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/How-to-make-Squid-3-3-8-a-transparent-proxy-tp4665624p4665627.html Sent from the Squid - Users mailing list archive at Nabble.com.
