Hi everybody.
I want to remotely use my computer at work using RDP from home . This computer is connected to the internet through a routerboard 750.
considering the DSL IP on the REAL NIC of the routerboard is 111.111.111.111 and the IP on the LAN NIC of the routerboard is 192.168.1.1 . (interfaces named REAL and LAN)
the IP of the microsoft pc is 192.168.1.2.
How can i go through this configuration.
i think that it is a natting issue if i am not mistaken.

any help is appreciated.

thanks for ur reply.
I added this line of code to the terminal of the router using winbox but it is not working. when i enter 111.111.111.111:3389 in my browser or using mstc with IP 111.111.111.111 i could not connect.
i even updated this line of code to :
add chain=dstnat dst-address=111.111.111.111 protocol=tcp dst-port=3389 action=dst-nat to-addresses=192.168.1.2 to-ports=3389 comment=“” disabled=no
also nothing happens .

Do you have firewall filters in place blocking that traffic?

add chain=input connection-state=invalid action=drop comment="drop invalid" disabled=no 
add chain=input connection-state=established action=accept comment="allow packets" disabled=no 
add chain=input connection-state=related action=accept comment="allow related" disabled=no 
add chain=input in-interface=Lan src-address=192.168.40.0/24 action=accept comment="Allow Lan" disabled=no

According to that you should be fine as long as you’re coming in from an address in 192.168.40.0/24 behind the interface named “Lan”. Are you?

Sorry i did not get u .. but what i want is to connect from outside the network .

Then you’ll have to add rules in the input chain that permit that.

i created pptp connection and i can connect normally from home to my routerboard using this connection
Can i benefit from this connection to make the rdp cpnnection ?

Yes, you could. If your PPTP client has a route to the subnet the RDP server is on you can connect to it via its private IP address.
