Hello, Sorry for the many Ccs, but I hope to reach all parties involved. I want to do traffic shaping with NAT and I wanted to do it with IFB instead of IMQ [1]. I tried a lot of things but now I am stuck (and maybe confused). The setup: eth0 eth1 WAN/(Internet) <-> Linux Router <-> LAN Linux router: - does NAT for the LANs - runs local processes

Hello! My goal is to setup an ingress traffic shaping on my PPPOE DSL line with ifb. My old imq stuff used iptables marks (like ''iptables -t mangle -A PREROUTING -p tcp --sport 22 -m length --length :500 -j MARK --set-mark 31'') to classify the traffic and since i am lazy, i tried to to reuse them with ifb. But no luck: iptables marks the packets well, but tc

Hello I''m trying to switch from IMQ to IFB but I have a problem with traffic marked by ipp2p module. Looks like when traffic is redirected from ethX to ifbX it looses information about MARK. Here''s what I do to get ingress traffic to go to ifb interface: $TC qdisc add dev eth1.42 ingress $TC filter add dev eth1.42 parent ffff: protocol ip prio 10 u32 \ match u32 0 0

How to use IFB as replacement of IMQ There is not much documentation about it Please explain with example -- Failure seldom stops you. What stops you is the fear of failure. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hello What I''m looking for is how to configure the Linux QoS module to do global rate limitation for two (or more) 802.1q pseudo network devices. I naturally suppose there is a possibility with IFB. I don''t want to use IMQ because it''s not integrated to my kernel v2.6.21.1 and I didn''t find IMQ patches for it nor for the iptables package I use (v1.3.7).

Hi all. I''m using Jamal''s ifb virtual interface from new kernel. Redirecting incoming traffic from external interface like that: # tc [blahbla] match u32 0 0 flowid 1:0 action mirred egress redirect dev ifb0 to ifb to shape it. The problem is that I''m using MASQUERADE by netfilter also. That redirected traffic coming from internet gets to ifb _before_ DNAT is done.

Hi, I am trying to do some simple ingress limiting based on fwmark. I know the ability and sense to do INGRESS limiting is ehm... limited ;-) but still I want to try it. I tried several things. === 1 === tcq ingress handle ffff: tcf parent ffff: protocol ip prio 1 handle 1 fw police rate 12mbit burst 10k drop tcf parent ffff: protocol ip prio 1 handle 2 fw police rate 10mbit burst 10k drop

Hi Roy, Strange. "kernel will resend then together with new ones" - this is interesting, since the firewall DOES know how to drop locally generated packets and the kernel doesn''t attempt to retry them. I am not an expert on this, but I think it might be interesting to check how the firewall does this. Another option would be to trick the kernel that the packet has been

Hey Marek, I´know that i must to works whith the INGRESS (instead of EGRESS), i´ve well formed my kernel. My others TC rules for source IP address (not for MAC address) does work fine...!!!, the problem is whith the MAC because is a not "IP PROTOCOL" and for that i must to use the "u32/u16 match" to solve it, and if i make an analogy from my others INGRESS rules applied to Src

Is IFB realy replacement of IMQ Please Guide -- Failure seldom stops you. What stops you is the fear of failure. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hey folks, I stumbled across the Mastershaper project ( http://www.mastershaper.org/ ) but I have a little problem: I wanted to shape the traffic coming from the router itself aswell as coming from the LAN behind the router, for that task I need IMQ, but with IMQ iptables-(layer7)-matching is not possible. Now I''ve talked with the programmer and he said the following: >The problem is

I''m trying to set up a shaper that can shape the inbound traffic to around 40 subnets, that hang on 3 different interfaces of the router. As Linux can''t do ingress shaping I''m left with having to set up 3 seperate shapers, one for each internal interface. This is not completely optimal as I''ll have to limit each of the 3 interfaces to 1/3 of the total

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

Hi, I''m trying to activate IFB device support in a 2.6.17 kernel from Debian Sid. I read that IFB device is the replacement for IMQ device, but I haven''t found any useful documentantion on how to activate this feature and the kernel documentation lacks of this information. I remember that IMQ could be activated in the ''Network devices'' menu in 2.6.8 kernels,

I''ve made some tests... eth2 is my internal interface, LAN is connected here. Before I had IMQ device in AB mode... PREROUTING [A]fter NAT, POSTROUTING [B]efore NAT. I want the same situation on ifb. I do this in this way: --- # incoming traffic here from LAN is before NAT tc qdisc add dev eth2 handle ffff: ingress # outcoming traffic here from WAN is after NAT tc qdisc add dev eth2

There is an new version of iproute2 for testing. http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.10-ss050112.tar.gz Mostly simple merges, but could have some issues.

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a
