#7 Shapper outgoing band using MASQ IP.

[Jozeph Brasil]

Hi,

Im using CBQ to shapper bandwidth in my small
network. In the same srv I have IPMASQ and CBQ,
two network cards (eth0, eth1).
The shapper from INCOMING BAND is working ok. The
problem is in OUTGOING BAND... whats necessary to
do to make it work.... :)

Thanks for anyhelp.

you need too just add the IP address out like

RULE=10.10.1.123 # from this address
RULE=10.10.1.123, # to this address

if you do a dump you would see that only the internal IP
address show up on 1 interface.

tcpdump -i eth1 | grep -i -I 10.10.1.*

would show all the traffic going on the eth1 interface
if the outside interface was eth0, you would not see any of
the 10.10.1.* addresses. so any RULE on eth0 would fail to
happen

I will try to share some test I made here!

I'm using Redhat... I tried in 7.3/8.0 and 9.0 versions and all
of them has the same problem.

My computer is a Athlon XP2000+/2 x 3Com 3c905BTX
cards/Asus A7N266 motherboard/256mb DDR/ Kernel 2.4.9,
2.4.18-9 and 2.4.20....

First I configured my interfaces with NAT'ed ip address... like

200.200.200.200 (for example) --- eth0 (linux) eth1 -----
192.168.1.1

iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE

CBQ version 0.72 and Download shapping works fine... and
upload was not shaped... (yes! I configured corretly with ","
at end of RULE in cbq config file).

After many tests..... I tested using valid IP Address...

200.200.200.200 --- eth0 (linux) eth1 200.200.201.1 -----
200.200.201.2 (notebook workstation)

And upload works fine!!!

Well... After many many many many tests ;) When iptables
with nat command is executed the CBQ is not shaping
bandwidth of upload connections..... Even if the notebook use
the valid IP... just execute iptables -t nat... and upload shape
stops work.

I'm thinking that this problem is with tc and not with CBQ...

Anyone has the same problem??? Anyone has any solution?

check out request id: 964549 ...

the comment I gave there might help you..

upload shaper won't work after NAT... it's so obvious... you
guys try to shape the upload on the same server you do the
NAT... well.. on the outgoing interface the local addresses
are already translated to the server's ip address... the
shaping is impossible, cuz there are no local addresses on
the outgoing interface...

My solution is rshaper.o working togheter cbq.init. BUT its it a
solution that ONLY works in 2.4 kernels. (rshaper.o do not
compiles in 2.6 kernels :-( )
Please Kutsnetzov give us a better solution in cbq ! We love
cbq.init !
