That's not messed up, that's what it's supposed to do.

The __pptp_server_ip__ (you don't say what it is) should be the inner,
or tunneled IP address to the server's tunneled interface.

No they shouldn't, because it probably isn't routable. It may be
that your local IP network and the remote tunneled IP network are the
same. That would cause you problems. If your connection is dropping
then it may be that your destination is behind a firewall. It's hard to
tell exactly what is going on with the limited information here.

That's not the problem to solve. The most common problem is setting up
routes to the tunneled destination. You probably need to add some
static routes to the remote networks. You can do this by adding a shell
script to /etc/ppp/ip-up.d directory:
# cat 70-routes.sh
#!/bin/sh
# Used parameters and environment variables:
# $1 - interface name
# $6 - ipparam name
case $6 in
ipparamvalue)
ip route add 10.0.0.0/8 dev $1;;
