Port forwarding - dyn IP

RouterOS General
1

Hello,
I know that my problem is popular adn seems to be very easy, but I don’t cant manage with it.

My conf:
DSL (dynamic IP) — MT – WLAN (10.1.1.0/24)

I just want to forward port (for example 8080) to my localhost (http server on my PC) - 10.1.1.20:80.
How can I do it?

[admin@test] /ip firewall nat> add chain=dstnat action=dst-nat to-addresses=10.1.1.20 to-ports=80 protocol=tcp in-interface=ADSL dst-port=8080

Change the value of ADSL to match what you called your WAN interface.

Cheers!
