i am using mikrotik RB3011.
i have one OLT directly connected to my microtik ETH1 port as WAN port. And I can Access Internet.
i have public ip too.
i want to forward my OLT ip to public ip so i can access My OLT from Anywhere.
My Mikrotik RB3011 is not server. its configure as Normal router broad with PPPoE to access internet.
MY main Router board as radius server is at different Location.
first you have to have DDNS and flow port forwarding
on (Dst. Port) put your OLT port
on (To Addresses) put your OLT and port
Use IPv6 and move on with your day.
