Hello, It's not the first time I ask for this, but I didn't see any answer. I have two proxies. They have Ips 10.105.x.y and 10.105.x.y+1 The outgoing is an upstream proxy. My problem is: They try to reach by themselves URL with: 192.168.*.* instead of forward them to the Upstream proxy. 1139206331.003 179161 10.104.x.* TCP_MISS/504 1490 GET http://192.168.37.10/icons/parent.gif - NONE/- text/html 1139206331.003 179123 10.104.x.* TCP_MISS/504 1492 GET http://192.168.37.10/icons/archive.gif - NONE/- text/html 1139206331.003 179119 10.104.x.* TCP_MISS/504 1486 GET http://192.168.37.10/icons/text.gif - NONE/- text/html 1139206331.003 179119 10.104.x.* TCP_MISS/504 1492 GET http://192.168.37.10/icons/unknown.gif - NONE/- text/html I really need a solution.
