Hi, On a dual stack network interface I’m interested in using squid as a ipv6 only forward proxy. My general understanding was that squid will prefer to use ipv6 whenever available, but I’m having issues with squid seemingly preferring ipv4 in some cases. I have two examples, where it proceeds using IPv6 for the first and IPv4 for the second. From the looks of it, they both successfully receive A and AAAA records, but how can I basically force squid to use IPv6?
Squid obeys the IPv6 specifications which still require IPv4 transition capabilities. Including whether you are on an IPv4-only or IPv6-only or Dual-Stack network.
The best way to make Squid IPv6-only is to make the machine it is running on IPv6-only.
Alternatively, to setup a firewall rule matching the proxy by PID/UID to reject TCPv4 connections with an ICMP "(3) Destination Unreachable" packet.
