Redirect All incoming request to specific internal IP addres

Hi people,
can anybody help me?

I want to redirect all incoming request from Internet to specific Internal IP address.
I prepare already this:
/ip firewall nat add chain=dstnat dst-address=1.1.1.1 action=dst-nat
to-addresses=2.2.2.123

(1.1.1.1 external IP, 2.2.2.123 Internal IP)
but it wouldn’t work. What can be the reason?

More info: the external IP address is with 29 mask, internal is with 24.

At home I have the same schema and it is working well, but the difference is that MT at home is DHCP server.

Did you also configure the corresponding srcnat rule for the outgoing traffic? See the 1:1 NAT example at
