My configs have always consisted of http_port 80 accel vhost.. With the latest 3.5.17 (I guess) if you don't list 0.0.0.0:80 squid won't even attempt to listen, talk on ivp4.. So adding 0.0.0.0:80 allows it to at least talk via ipv4. This seems wrong, odd. I understand you are removing methods to disable ipv6, however forcing folks to us only ipv6 seems like a stretch :) Thanks Tory CentOS 7 squid-3.5.17-1.el7.centos.x86_64 _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
