I have a tc script which splits the bandwidth in 8 leaf classes based on IP filtering. The script looks like this: tc filter add dev $LAN_IFACE protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.0.121 flowid 1:11 The separation works excellent for downloads, but for uploads, it is ignored... Can you tell me how to deal with it?

For uploads, the packets are natted. So the src address is rewritten. You can get around this if you mark the packets with iptables when they enter the box (so you have the real src address) and use that mark with the fw filter.

cRTP and RTP or other Header methods of header compression
Hi
I have the following challenges that I need to solve and I did some reading
and I need some input on this as well.
I have a VSAT link at my office and we all know that the more bandwidth we
have the happier we are. I am already
doing some Qos using HTB and IMQ on the link to prioritize specific traffic
and the next challenge I received is
to optimize our Cisco ATA 186 VoIP adaptors. I was looking at doing header
compression between my remote
sites and I was wondering if there is anyone out there that played around
with RTP for Linux and is it possible.
What I typically want to achieve is to have a linux bridged device that
collects the voice packets from the Cisco
and then strips it of all the headers and sends it off to my other office to
another linux bridge and cisco ATA.
Cisco ATA ---- Linux Bridge ---- VSAT --- Internet ----- VSAT -----
Linux Bridge ----- Cisco ATA
I was also thinking about doing PPPoE between the two Linux Bridges and from
what I have read they tell me
that I will only get 5 -10 % bandwidth saving. Is there any other method
that you guys recommend that I have
a look at.
Hope to hear from you soon
Thomas

Re: cRTP and RTP or other Header methods of headercompression
Hi IPSec with compression is a good idea, but it still add''s AH/ESP packet headers to the system that I would like to avoid. And voice data is already compressed and no further compression will happen. We are limited to bandwidth usage and packet header compression was one of the options that I am looking at .
