RV220W PPTP Start IP Address must not be in the subnet of LAN:192.168.1.1/255.255.255.0

Question

Hello,
I start setup of new RV220W Wireless router.
I want to provide access to internal network via PPTP.
But gettting error 'PPTP Start IP Address must not be in the subnet of LAN:192.168.1.1/255.255.255.0'.
I reviewed the forum and some user's says what they can fix this issue, but I cannot found the way how to do it.
Details of router:

How I can enable assigning the IPs from LAN network to the PPTP Server?
Thank you!

Hi,
This is a change done explicitely starting firmware 1.0.4.17. It is not a bug. This appears to be by design. PPTP peer networks are now treated as a routed subnet. It is unlikely that this will be changed.
But nevertheless there is a workaround to configure the PPTP range in the same subnet as your LAN:
1. Configure LAN IP subnet different from what you will use, for example 192.168.2.0/24
2. Configure DHCP pool for PPTP client as needed for example 192.168.1.100-192.168.1.110
3. Go back to LAN interface and change LAN IP to desired one: 192.168.1.0/24 and pool 192.168.1.2-192.168.1.99
4. This way there will be no error on GUI 
5. PPTP client will receive IP address from the same subnet as LAN interface of the RV220W
