If you want to limit incoming traffic have a look at the policer example in LARTC, there are other ways using ifb/imq, but I don't know if dd-wrt will have those.

[LARTC] rate limiting netmask w/ dd-wrt
I'm trying to setup a DD-WRT router (www.dd-wrt.com; embedded micro-device linux for the uninitiated) to rate limit all the traffic it receives from its wi-fi interface. I followed the instructions from the cookbook section on rate limiting (http://lartc.org/howto/lartc.ratelimit.single.html), but it doesn't appear to be working. I tested by checking my laptop's bandwidth on http://www.speakeasy.net/speedtest/. Here's the commands I issued to tc: # tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit # tc class add dev $DEV parent 1: classid 1:1 cbq rate 512kbit allot 1500 prio 5 bounded isolated # tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip src 192.168.1.0/24 flowid 1:1 I replaced $DEV with each interface name in succession, as I wasn't sure which to use. Here's the output of ifconfig from the router: # ifconfig br0 Link encap:Ethernet HWaddr 00:16:01:59:EF:00 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:114200 errors:0 dropped:0 overruns:0 frame:0 TX packets:125307 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14568079 (13.8 MiB) TX bytes:71752923 (68.4 MiB) eth0 Link encap:Ethernet HWaddr 00:16:01:59:EF:00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:64266 errors:0 dropped:0 overruns:0 frame:0 TX packets:54720 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:65677538 (62.6 MiB) TX bytes:12736990 (12.1 MiB) Interrupt:4 eth1 Link encap:Ethernet HWaddr 00:16:01:59:EF:02 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:117891 errors:0 dropped:0 overruns:0 frame:253671 TX packets:133961 errors:3 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:16589572 (15.8 MiB) TX bytes:75539860 (72.0 MiB) Interrupt:2 Base address:0x5000 loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MULTICAST MTU:16436 Metric:1 RX packets:46 errors:0 dropped:0 overruns:0 frame:0 TX packets:46 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5328 (5.2 KiB) TX bytes:5328 (5.2 KiB) vlan0 Link encap:Ethernet HWaddr 00:16:01:59:EF:00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:5570 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:1086810 (1.0 MiB) vlan1 Link encap:Ethernet HWaddr 00:16:01:59:EF:01 inet addr:192.168.10.138 Bcast:192.168.10.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:64281 errors:0 dropped:0 overruns:0 frame:0 TX packets:49178 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:64522436 (61.5 MiB) TX bytes:11432967 (10.9 MiB) Can anyone tell me what I'm doing wrong here?
