i m using cisco 2821 as pptp server. the internal network is 192.168.0.0/24, 192.168.1.0/24 and 192.168.2.0/24. remote ip pool is 192.168.0.200-250
internal dns server 192.168.0.1-2
the problem is when pptp user behind 192.168.x.x network and using 192.168.x.x as dns server. (quite a number of home users use 192.168.1.1 as gateway) the pptp user will use their own dns server but not internal. it result the pptp user cannot reach internal servers.
