Shapper outgoing band using MASQ IP (part 2 ;) )

Anonymous — Fri, 18 Jul 2003 16:18:41 -0000

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?
Sorry for my bad english...
