i am using PPPoE and everything works fine except that.
it looks like ppp has problems with reverse-proxies.

i tried two different kernels : with and without firewall

i run ppp as root "/usr/sbin/ppp -quiet -ddial dsl"


tcpdump show that the i.e. gmx-server sends some kind of response
but then nothing happens.

 I don't see anything to believe this is related to ppp(8). Afterall,
 you show us your telnet(8) to the server worked fine.
