Sorry I'm just back. I don't understand functionality of tcp_outgoing_mark. How it works. how to use. Can I use this feature to set dscp field for every packet leaving squidbox and go to the client? do we need to do something with iptables after set tcp_outgoing_mark tag on squid? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Error-using-tcp-outgoing-mark-tp4658748p4664052.html Sent from the Squid - Users mailing list archive at Nabble.com.
