One of the most popular PPTP client problems is the routing loop created 
by using same server address inside and outside of tunnel. In such case 
address inside of tunnel with /32 netmask usually more preferred for the 
system and it makes all tunnel traffic wrap inside tunnel itself causing 
unpredictable results.

Addresses inside and outside of tunnel _MUST_BE_DIFFERENT_!

In some cases problem can be workarounded with some firewall forwarding 
or some other alike techniques.
