I recently purchased a MikroTik router, it works great! However, I haven't been able to make my web server work from outside my lan

I'll explain better:

I have two domains in my disposal, before I switched to Mikrotik, the were working perfectly and all my websites were online. Since I changed the router, every time I try to access my websites from outside my lan, my websites can't be found.

I have my websites domains associated with a dynamic dns provider, I managed to create a port forwarding rule to redirect all my incoming traffic from port 80 to my web server, and it works, but only when I'm connected to my MikroTik router.

Is there something else I have to do?

PD: I also created a static dns rule in my router with my domains to associate it to my webserver (which is behind my router)

PD2: All I want is to redirect requests from outside to my webserver...
