FWIW: PPTP is a transport protocol. It has nothing to do with Microsoft
NetBios, Browsing, Workgroup/Domain names, etc... Use the FQDN.

The netmask statement above is useless when using a Windows based PPTP
client. Your PPTP client is going to assign the class a based netmask as you
have shown above. This has been a source of irritation for me too.

Uh!!! Why are you assigning the same IP's to both the remoteip and localip.
That will never work. Try the following:

localip  10.0.0.200
remoteip 10.0.0.201-250
