Hi, I recently installed a new server using kernel 2.6.5 and I need to control the bandwidth of peer-to-peer programs like Kazaa... I already do that on another server and just copied the script to the new one. Here is an example: # iptables -t mangle -A PREROUTING -s 192.168.0.1 -j CONNMARK --set-mark 1 iptables: Invalid argument I am using the last stable version on iptables and POM. What am I doing wrong? -- Marcelus Trojahn
