[pptp-server] Error 778: Unable to verify the identity of the server

[Mark Burring]

Well there are several users that wish to use it at the same time. The
reason I used a range of the local IP's is because its in the Redhat
PopTop howto. Previous experience with PPPD does tell me that doing this
way is bad but giving out local ip's smooth's things over with the M$
PDC's

why don't you try with one ip address rather than a range at the local
ip. 
just give a try.
