Thank you for the update advice everyone, and for the squid.repo suggestion, that worked very nicely to update squid using yum. I'm now using the latest version (3.3.5) however it seems a few of the lines in the rest of my squid.conf are obsolete - so although squid starts with the current squid.conf it no longer seems to permit connections. I've tried commenting out the obsolete lines (noted below) - here is my full squid.conf any observations, please? >>>>>>>>>> logfile_rotate 5 ## this line is obsolete in 3.3.5 ##emulate_httpd_log yes server_persistent_connections off forwarded_for off ## declare an acl that is true for all ipv6 destinations acl to_ipv6 dst ipv6 ## deny ipv4 access http_access deny !to_ipv6 ##tell Squid to listen on sequential ports and to designate a name for each inbound connection. http_port 109.xxx.xxx101:3128 name=3128 http_port 109.xxx.xxx101:3129 name=3129 http_port 109.xxx.xxx101:3130 name=3130 http_port 109.xxx.xxx101:3131 name=3131 http_port 109.xxx.xxx101:3132 name=3132 ## proxy server client access - this is YOUR originating IP, repeat the line for multiple IPs acl mynetworks src xxx.my.ip.here http_access deny !mynetworks ## 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[2001:::::::ipv64] user4 tcp_outgoing_address [2001:::::::ipv65] user5 ## disable caching cache deny all ## this line is obsolete in 3.3.5 ##acl manager proto cache_object request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-how-to-link-inbound-IPv4-multiple-port-connections-to-unique-outbound-IPv6-s-tp4660190p4660213.html Sent from the Squid - Users mailing list archive at Nabble.com.
