[pptp-server] Problems with iPAQ clients?

Hi!

You can be lucky. My iPAQ won't even connect to our LiNUX pptp server. No
way....I have tried it over cradle, over GSM...Nothing...It halts on point
where PC is sending ppp config req to iPAQ but then it seems like it doesn't
get any reply and it fails.

All other clients work OK (Win98, Win2000...). Did you have to change
anything particular in configuration of PPP or PPTP server on LiNUX??

Regards,
Alen Salamun
