As the title says I need to block all the connection to mikrotik router from outside except connection to VPN server. Then allow Remote desktop to LAN's system over VPN(either L2TP/IPSec or PPTP) from outside LAN.
What would be the rule in Mikrotik router's Firewall to block all the connection except rdp over vpn?
Addition info:
There is LAN setup in our office and the final gateway is Mikrotik router. I know how to create VPN server, VPN client in clients system and make rdp from clients system. I want that external firewall should only let in connections to VPN server vpn firewall rdp mikrotik
