masquerading problems under 2.4.x works for windows and not linux?

[Marcio Gomes]

Hi,

I'v having problems with this architeture.

Linux 2.4.0-test3-pre1 ( pre2 don't compile, I
will test with pre9 as soon as possible ) 
In 2.4.0-PREandXXX I have similar problems.

Topology of network.

Linux------LinuxSNAT/MASQ-----ppp-----Network-----A/B/C

If I load Nat modules, and maquareade/Snat the
linux conecctions... traceroutes from Linux
to A/B or C don't recieve ureachable destination
from A/B or C.

With Iptraf I can see the traces UDP packets
arriving in A/B or C. 

Machines in middle of trace, are Ok... 

In 2.4.0-test1 I reproduce the same thing.. But
machines in middle of trace don't answers with
dest. unreachable to. In 2.4.0-test3-pre1 and
test2 only the target machine don't answer. 

In 2.4.0-test1, I see some problems with ping (
ICMP ) Packets... but now it is ok. 

If I reboot Linux in Windows, tracert works
fine. 

Another problem is with iproute2+tc, 

In 2.2.16 series I can delete the root qdisc with
out delete the qdisc/class/filters after thar.

In 2.4.0XXXXXXXXXXXX series, it give me a kernel
panic.


Thank's
