Andres, Because there is no way to distinguish between a local-only network and one using NAT without actually trying to connect to the IPs (which is exactly what Squid is doing - up to the limit of forward_max_tries). The problem is identical and far more widespread in IPv4. Disabling IPv4 whenever RFC1918 addresses were the only ones assigned would cut a huge number of networks connectivity.
It simply comes down to the fact that despite some mistaken opinions to the contrary, IPv6 is mandatory for any network that wishes to communicate with the www. IPv4-only networks (even just on the global facing part) will face more and more inability to communicate as time passes. We can juggle some numbers to workaround the pain for a while. But in the end IPv6 is mandatory. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid3 in Ubuntu. https://bugs.launchpad.net/bugs/1547640 Title: proxy tries ipv6 and gets 503 when no ipv6 routes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/1547640/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
