Hello! Squid 3.1.19. Our squid servers are dual stack IPv4/IPv6 since about a year, with this config "hack": tcp_outgoing_address x:x:x:x::x to_ipv6 tcp_outgoing_address x.x.x.x !to_ipv6 acl to_ipv6 dst ipv6 http_access allow to_ipv6 !all But now our users are tired of webs that announce IPv6 addresses but don't answer on port 80 on these addresses. So I enabled dns_v4_first in the config and did squid -k reconfigure. But it didn't help, we still get IPv6 timeouts towards misconfigured web sites. I'm guessing that dns_v4_first and the ipv6 config above are mutually exclusive? Should I change the tcp_outgoing_address line to just this: tcp_outgoing_address x:x:x:x::x tcp_outgoing_address x.x.x.x and remove these lines: acl to_ipv6 dst ipv6 http_access allow to_ipv6 !all Or will this remove all of our IPv6 connectivity through squid? Thanks! -- Peter Olsson pol@xxxxxxxxxxx
