Hello Folks , Im trying to mark outgoing squid request based on Mark linux matching . I added to squid conf : qos_flows mark local-hit=0xd7 qos_flows mark local-miss=0xd7 -A OUTPUT -m mark --mark 0xd7 -j ACCEPT But on iptables there is no match with the mark 0xd7 Im testing marking with squid and matching with iptables but its not matching , always statistics = 0 on linux iptables That mean its not matched . Squid version is 4.8 Also squid was complied with '--enable-zph-qos’ flag So not sure if I need specific config for squid . Following : https://wiki.squid-cache.org/Features/QualityOfService Based on it we need kernel patch for TOS , but I dont need TOS , I just need Layer 3 DSP , Linux mark rule based . i even tried to match traffic by mark and connmark and both did not help . -A OUTPUT -m mark --mark 0xd7 -j ACCEPT -A OUTPUT -m connmark --mark 0xd4 -j ACCEPT So both rules above was not able to pickup squid marking . Any helping Team on this case ? Thank you _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
