I just purchased my first Mikrotik router, a RB750. I am trying to setup a port forward on it (actually a few) but the first one I am doing and testing is Windows RDC.
I have setup a NAT rule in WinBox with these options:
Chain: dstnat
Protocol: 6 (tcp)
In. Interface: ether1-gateway
Action: dst-nat
To Addresses: 192.168.1.10
To Ports: 3389
Yet when I try to connect it doesn’t work. Am I missing another step?
The only stupid question is the one you never ask.
That being said, I too am a brand new MikroTik user and I have attempted to configure the RDP 3389 port forwarding in NAT just as you described with the same result. Hopefully someone nice will answer this for us without berating us for being n00bs!
Edit your rule and fill out the field for dst-port so that the router knows what traffic to NAT. Currently you’re telling it to forward all TCP traffic to port 3389 on 192.168.1.10. Also, if you’re translating port x to port x, there’s no need to specify to-port, though it doesn’t hurt.
If that still doesn’t work, post the output of
/ip firewall filter print
/ip firewall mangle print
/ip firewall nat print
Are your lan behind a srcnat masquerade? What is your firewall setup?
If you have set up a firewall, then make sure that you open for the port in the firewall first. and then do the forward in the dst-nat. It should look like this:
/ip firewall filter
add action=accept chain=forward comment=“” disabled=no dst-port=20-21 protocol=tcp
/ip firewall nat
add action=dst-nat chain=dstnat comment=“” disabled=no dst-port=20-21 in-interface=GTS protocol=tcp
to-addresses=192.168.1.10 to-ports=20-21
