PPTP VPN Connection that can see two subnets

I have a Mikrotik 750 that has the following:

ether1: wan
ether4: private101 (192.168.101.0/24)
ether5: private105 (192.168.105.0/24)

dhcp runs on ether5 (private105)

I have setup my pptp server and I can create a vpn connection and succesfully get assigned an ip from the private105 address pool and can ping things on the 105 subnet but I also want to be able to get to the private101 subnet from the vpn. If i was using static ip for the vpn connection I could create a route but I need to use a pool of addresses.

Please help and thank you.

What about default gateway on client to pass throu all traffin on vpn, in this case you do not need to have specific route on client.

The client is a Windows 7 computer that I have turned the default gateway off for the vpn connection so that normal internet traffic doesnt have to go through the vpn.
