<div id="RTEContent">Hello lartc maintainers and users!<br> I have a router with two NICs. One NIC is connected to the Internet and the other to my internal LAN. I made a script for priorizing interactive traffic. The script matches TOS Minimize-Delay for priorizing interactive trafic, and fwmark for metropolitan packets.<br> I have two root classes (simulating two circuits) : 1:1 for internet and 1:3 for metropolitan.<br> When I watch -n1 tc -s -d qdisc show, the classes that belong to metropolitan traffic (FE) on the two interfaces are not sending nor receiving any byte...<br> Can someone help me out this situation? I list my tc and iptables scripts below (for some reason I could't attach them - "Invalid file").<br> Thank you in advance!<br> ---------------------------------------------------------------------------------------------------------------------<br> my_script.sh:<br> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="Generator"
