I'm trying to setup a squid proxy that will accept multiple inbound connections on one IPv4 across a range of ports, and for each port connection to connect out on a unique IPv6 address.
I've named each port connection, and designated an ACL based on the connection name, and then I've tried to define an outgoing IPv6 for each. The script below works, in that it accepts connections on the different ports and routes out via IPv6 however, all outbound connections use the same IPv6 (user5) even though there are different ipv6 defined per user - the wierd bit is that even if I comment-out that user5 IPv6 from squid.conf, it still gets used for outbound connections.
Can anyone see whats wrong here? (using Squid 3.1.1 on Centos 6 64bit)
## declare an acl that is true for all ipv6 destinations acl to_ipv6 dst ipv6 ##tell Squid to listen on sequential ports and to designate a name for each inbound connection. http_port 241.xxx.xxx.101:3128 name=3128 http_port 241.xxx.xxx.101:3129 name=3129 http_port 241.xxx.xxx.101:3130 name=3130 http_port 241.xxx.xxx.101:3131 name=3131 http_port 241.xxx.xxx.101:3132 name=3132 ## designate acl based on inbound connection name acl user1 myportname 3128 acl user2 myportname 3129 acl user3 myportname 3130 acl user4 myportname 3131 acl user5 myportname 3132 ## define outgoing IPv6 per user tcp_outgoing_address [2001:::::::ipv61] user1 tcp_outgoing_address [2001:::::::ipv62] user2 tcp_outgoing_address [2001:::::::ipv63] user3 tcp_outgoing_address [2001:::::::ipv64] user4 ##tcp_outgoing_address [2001:::::ipv65] user5 ##this last IPv6 always gets used for all outbound connections, even if commented out
