Is PPTP the only VPN option from this thing? I just find PPTP rather
distasteful, since the only encryption possible is named "Microsoft",
and it has a non-free license. I prefer OpenVPN, because it uses
OpenSSH for encryption.

A strength of PPTP is the server-client model for scalability, but if
you're the only user you don't need that.

I have had the same issue on pptpd's I maintain. Funny thing is that
when I don't require encryption I get it at 128-bit!

What else is in there? I use these:
#v+
+chap
+chapms
+chapms-v2
#v-

You might also want to try "debug" until you get things working.

"debug" will show you the dialogue between server and client wherein
they discuss what sort of encryption is to be used. For me that logs to
/var/log/debug, but that of course depends on your syslog.conf.

I guess I haven't helped much. Like I said, I really dislike PPTP. :)
They (poptop.org) do have a mailing list which probably has more
posters who understand PPTP and pptpd. I got mine working and leave it
alone as much as possible. :)
