Hi!
Fist, thanks a lot for your reply!

I'm not sure why it's happening but your PMac G4 system is sending reset packets in response to the responses from the server.
Ouch! That's indeed very strange. I can only repeat that it *did* work using isdn, so apparently there is some pppoe related porblem?
Have you tried using an SNAT rule temporarily on your POSTROUTING chain to see if the problem is with the MASQUERADE rule?
Same effect - replaced the masquerade rule by
ppp0ip=84.44.130.37 iptables -t nat -A POSTROUTING -s 192.168.42.0/24 -o ppp0 -j SNAT \ - --to-source $ppp0ip
but tcpdump still reports

The modules ipt_MASQUERADE and iptable_nat *are* loaded, btw.
Also, what is your "echo 2 > /proc/sys/net/ipv4/ip_dynaddr" doing for you?
I don't see any messages in /var/log messages or in dmesg, if you mean that. Or did I miss your point here? I found some howto where they stated this would be necessary...
You might want to check to make sure that reverse path filtering
is not turned on by default. You might also want to turn on verbose routing messages to see if there is any thing useful being reported.
Hmmm, can you tell me how I actually check reverse path filtering and turn debugging on? Sorry, I'm neither a iptables nor a kernel guru :-/
Thanks a lot for your help,
cheers, Albrecht.
