Hi, My friend uses ipchains with kernel 2.4.21 :) It''s funny but it''s true. The problem is that he marks the packets and after this the tc filter doesn''t catch them. ipchains -A input -s 192.168.1.41/28 -j ACCEPT -m 0x2 -t 0xff 0x2 ipchains -A forward -s 192.168.1.41/28 -j MASQ -m 0x2 ipchains -A input -s 192.168.1.240 -j ACCEPT -m 0x3 ipchains -A forward -s 192.168.1.240 -j MASQ -m 0x3 And the filter: tc filter add dev eth0 protocol ip parent 1:0 handle 2 fw classid 1:2 And after all no packets traverse the following class: tc class add dev eth0 parent 1:0 classid 1:2 htb rate 1kbit ceil 2kbit prio 20 (rates are examples only for testing). Any ideas?
