- Transparent proxy is not available.
-
+ Transparent proxy is done via NAT at the OS level and is not available (yet) in IPv6.
+ Squid will ensure that any port set with transparent or tproxy options be an IPv4-only
+ listening address. Wildcard can still be used but will not open as an IPv6.
+ To ensure that squid can accept IPv6 traffic on its default port, an alternative should
+ be chosen to handle transparent traffic.
+ ie http_port 3128
+    http_port 3127 transparent

 NP: iptables <= 1.3.8 tested bad.
 SOLUTION: iptables/netfilter crew working on IPv6 support. Try again in a few months.
+WORKAROUND: squid will explicitly force an IPv4 listening address for transparent ports.
 
 
 PROBLEM: Sockets created with IPv4 'family' cannot be use for IPv6 *anywhere*.
