Hello, it seems, that filtering on nexthdr (TCP/UDP) content, especially src or dst port, is not working. The following has no effect on 2.4.16 or older (even 2.2) kernels: # tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match tcp dst 3128 0xffff police rate 40kbit burst 10k drop flowid :1 Even if # tc filter ls dev eth0 parent ffff: filter protocol ip pref 50 u32 filter protocol ip pref 50 u32 fh 800: ht divisor 1 filter protocol ip pref 50 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid :1 police 4 action drop rate 40Kbit burst 10Kb mtu 2Kb match 00000c38/0000ffff at nexthdr+0 looks reasonable, TCP connections to port 3128 are not policed. If I use "match ip dst <ip-address>" instead, the policing works. Port based matching isn't working for outgoing shapers either, as can be seen with the statistics functions. Any idea? Anybody with port based (etc.) filtering actually working?
