Hi there, 
 It appears you have the destination address pointed at the inside address of the firewall. Think rule flow from top to bottom; you want to allow_RDP on the WAN zone using the Outside WAN network on port rdp61138 and Forward it to 'Evan' in the LAN zone. 
 Change the destination host to your WAN adapter (Usually port 2) under Destination & Service 
 I assume the rdp61138 service is configured to listen on port 61188 and you want the firewall rule to redirect to port 3389, then you will need to check the box 'change dest port' under Mapped Port and set it to 3389.

Hi pieterknecht, 
 
 You may first need to check if the traffic actually reaches XG device or not. 
 Take a packet capture refer https://community.sophos.com/kb/en-us/123189 
 String : port 3389 
 If there is any traffic incomming from WAN then your Network Broder Gateway is forwarding the request and we can dig more in XG. If not then check your actual puclic address , your XG does not have a Public address and has a Private address which is Natted by another ISP device. 
 If you have access of such device then create a DNAT or Virtual host of the same to your XG's WAN interface. 
 If not then you may need to check with your ISP, you may simply google from local IP "What is my Ip ?" and it should tell you the Public address you would need to RDP to.
