While Squid appears to be trying to use the half-working IPv6 network you have available. Not that your Squid is apparently *successfully* performing the TCP SYN/SYN-ACK exchange to setup the remote server connections over IPv6. *Then* failing on the data packets. As a friend of mine is becoming famous for saying: "Welcome to your IPv6 transit network, whether you know it or not". > All the client are connected to a DC Windows 2012 server that manage > DNS,DHCP and AD. > The proxy server is not under the domain controller and have a static Ip > adress. > Any way I will try to run MTU Path and i will give you feed-back. > Other way would you advise me to installa nother version of Squid proxy? I advise looking into fixing the IPv6 on your network. Since Squid is getting as far as it does you can be sure there are other software on your network doing same, or possibly even getting working connections. Start with the firewall rules on your routers ASAP so that when you get around to fixing packet transit your normal security policies does not suddenly gain lots of holes. Amos
