Hallo, Peter, Du meintest am 12.07.11: >> How can you expect *machineS* to get a response from squid if >> network is down? > Proxy server. Squid accepts clients on inside interface and > connects to internet servers on outside interface. > Outside interface goes down with inside interface still alive. That was the option/switch offline mode on or offline mode off New versions of squid don't need this option; if the WAN interface is down the clients get their pages from the cache (or they get nothing if the wanted page is not yet cached). Viele Gruesse! Helmut
