VPN to MIKROTIK Router via WIFI Router

Hi All!
Im using MikroTik RouterOS v5.18 x86 on a Dell PC.
I have done the following:

[]Set Addresses
[
]Set PPPoE Client & Server
[]Set PPTP Server
[
]Make Profiles and Secrets
[*]SRCNAT MASQUERADE the IPs of PPPoE and PPTP POOL

Now the Problem is this:
I have the Setup as shown below
4 PCs Connected to RouterOS via LAN SWITCH
1 PC and Android Devices via Tenda W311R+ WIFI Router

I dont want to give anonymous access to internet via WIFI hence i set it to DHCP Client NOT PPPoE

The problem is that when i connect to VPN via the PC or the Android, VPN does not connects or if it does then there is no Internet Connection.
I have to Work with what I have got, so please do not ask me to buy a WIFI Card for the PC as i know it would make it much easier!

PS this is for a NON PROFIT ORGANIZATION, so you get the idea why i cant buy new stuff!

Can anyone help?

Hello!! is there anyone who can help?

Hi All!!
A little change in Question.
VPN is connecting through the WIFI Router but only via its Ethernet (Wired) Connection. Still not PPTP over WIFI.
VPN Pass through is supported by the Router, I connected to VPN Book via the same router successfully, but not to the local MikroTik PPTP Server over WIFI. Please Help!!! :frowning: :frowning: :frowning:
