pptp vpn issue cannot reach private ip subnet via public pptp address

I have a public subnet 14 ips. and pptp in the vpn on one of the public ips and can reach my machines on the public ips when i vpn in, However, I can ping the private subnet fine from my routeros box as it also has a second address on my private 192.168.11.x subnet.

Hoever, When i vpn in onto one of the public ip pools I am unable to reach the private subnet.. i do have a firewall..

the private subnet connects through one of my public ips on another router..

what else do i need to set up .. thanks

You’re going to have to post some of your configuration, there are too many possibilities. Ensure that you ‘x-out’ the first three octets of any public ip address, i.e. x.x.x.139.

This will allow us to be of further assistance.
