Hello, I'm having trouble configuring a forward proxy. My goal is the following: Only for one destination domain IPv6 should be used, otherwise IPv4. The proxy has multiple incoming IPs and multiple outgoing IPs, here is the relevant part of the squid.conf: acl port80 localport 80 acl port88 localport 88 acl port443 localport 443 http_port 10.0.0.54:80 http_port 10.0.0.54:443 http_port 10.0.0.59:80 http_port 10.0.0.59:443 http_port 10.0.0.59:88 acl ipA localip 10.0.0.54 acl ipB localip 10.0.0.59 # only somedomain.asdf via IPv6 acl domain_acl dstdom_regex -i \.somedomain\.asdf tcp_outgoing_address 10.0.0.93 ipB port88 tcp_outgoing_address 2001:cdba::3257:9652 ipB port88 domain_acl tcp_outgoing_address 10.0.0.54 ipA port80 tcp_outgoing_address 10.0.0.63 ipA port443 tcp_outgoing_address 10.0.0.59 ipB port80 tcp_outgoing_address 10.0.0.93 ipB port443 dns_v4_first on Expected behavior: A connection on http_port 10.0.0.59:88 is requesting a domain matching regex "\.somedomain\.asdf", then the first matching tcp_outgoing_address is used, namely tcp_outgoing_address 2001:cdba::3257:9652 ipB port88 domain_acl Actual behavior: A connection on http_port 10.0.0.59:88 is requesting a domain matching regex "\.somedomain\.net" and tcp_outgoing_address 10.0.1.54 ipA port80 is used. If I change dns_v4_first from on to off, tcp_outgoing_address 2001:cdba::3257:9652 ipB port88 domain_acl is used for any incoming http_port. Does anyone know why squid behaves the way it does ?
