port forwarding issue

Hello,
I have two devices in my LAN connected to microtik router and the microtik is using pptp vpn.
1, I want to access the gui of the devices in the LAN from remote place. When I tried with my vpn dedicated IP it shows site not responding
I have done firewall filter rules as follows
chain dstnat— protocol tcp ---- dst port 80 ----- Action dstnat — To adress : 192.168.5.11

but this doesnot working. Please help to solve this issue

You don’t need a port forward since you’ ve made a VPN. Most likely you’ve got a worng VPN configuration.
