Which all looks ok, but is there an "http_access" that allows anything other than the "CONNECT" method, such as: http_access allow MSN_hosts http_access allow MSN_domains http_access allow MSN_net Not to mention any other sites / hosts / ports (Such as port 80) before the "http_access deny all", because whenever stacking ACL's there is an implied "AND" operator, so each line only works like this: "Method is CONNECT" AND "Ports" AND "Destination is <list>" Otherwise DENY ALL is the likely culprit. >>> David Touzeau <david@xxxxxxxxxx> 2/8/2011 1:22 PM >>> Dear i Use squid 3.1.10 and i would like to allow MSN messenger pass trough squid According wikis i did this : # Permit MSN acl MSN_ports port 1863 443 1503 acl MSN_domains dstdomain .microsoft.com .hotmail.com .live.com .msft.net .msn.com .passport.com acl MSN_hosts dstdomain messenger.hotmail.com acl MSN_nets dst 207.46.111.0/255.255.255.0 acl MSN_methods method CONNECT http_access allow MSN_methods MSN_ports MSN_hosts http_access allow MSN_methods MSN_ports MSN_domains http_access allow MSN_methods MSN_ports MSN_net But MSN still did want to connect with these errors: 192.168.82.173 - - [08/Feb/2011:10:48:38 -04-30] "POST http://www.sqm.microsoft.com/sqm/messenger/sqmserver.dll HTTP/1.1" 403 1662 TCP_MISS:DIRECT 192.168.82.173 - - [08/Feb/2011:10:48:39 -04-30] "POST http://www.sqm.microsoft.com/sqm/messenger/sqmserver.dll HTTP/1.1" 403 1662 TCP_MISS:DIRECT 192.168.82.173 - - [08/Feb/2011:10:48:39 -04-30] "POST http://www.sqm.microsoft.com/sqm/messenger/sqmserver.dll HTTP/1.1" 403 1662 TCP_MISS:DIRECT Where i'm wrong ??
