Hi all,
after weeks of waiting my UMTS Card arrives (web-search ensures
me that it will work - eg. le's Blog ...)
So I figured out how to configure ppp (it's not trivial! ;-)) and
after around 5 or 6 hours I get it run that way, that nslookup
& ping works ...
And that's all - here I stopped and can't get any progress.
I started some diagnostics why my web wont work, and detected
that packets larger than 229 byte payload via ping will swallowed
by the connection (I don't know where).
I'll attach my ppp.conf, the log of ppp, the commands I used to test
and the according tcpdump output.
Any help would be welcome.
Best regards,
Jens
