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.

What software (pptpd, pppd and kernel) are you running on your server and on your client? -- Charlie ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
