NAY Help / 4g + 951U

Good Day everyone.

I have a small problem with a clients set up I just can’t seem to get past.

Here is how things are set up

Internet — > (4G router "192.168.1.1/24*) ------> (Mikrotik 951-2Hnd192.168.1.2/24-ether1 **ether 2 Main| 2-5 Slaved Off ether 2 and Bridge is in place for the wlan)(internal network range is 10.0.0.0/24

The problem i am experiencing is that on the first 4G router I have set up a dmz for all traffic to 192.168.1.2

I now need to set up RDP to a local machine from external, But i am having no joy in such.

I have setup the RDP correctly as I have done so on many other systems. Any help would be appreciated.
