I notice something unusual in the server logs:

http://sourceforge.net/mailarchive/forum.php?thread_name=20110407230946.GC6232%40us.netrek.org&forum_name=poptop-server

Apr  7 18:50:04 skyxen pptpd[2781]: GRE: Bad checksum from pppd.

Perhaps after that error your server is not sending GRE. I don't know, I'm 
not familiar with that error.

What software (pptpd, pppd and kernel) are you running on your server and 
on your client?
