Remote desktop services gateway Windows 2012 R2 and XG1115w

 Hi

Have someone got this to work smootly? I am getting crazy on this to get to work.
I am using firmware SFOS 17.0.1 MR-1.
I've followed this instruction: https://community.sophos.com/kb/en-us/126103

On this section: 

RDS Web Access Rule

1. Navigate to Firewall.
2. Click Add Firewall Rule and select Business Application Rule from the drop down menu.
3. Select the Microsoft Remote Desktop Gateway 2008 and R2 template
4. Fill in the required details:
   • Rule Name
   • Hosted Address
   • Listening Port
   • Certificate
   • Domains
   • Protected Server
5. Go to the Advanced section at the bottom of the Firewall rule and click the drop-down box beneath to Protection.
6. Now select Microsoft RD Web 2012R2

Hosted address is Port 1 which is lan. But I am not sure of that. And I cant use port 443 because port is used by User portal.
If using port 2 which is wan and 443 it says this policy is used by other policy. That Rule is RDS Web gateway rule

RDS Web Gateway Rule

   • Rule Name
   • Hosted Address
   • Listening Port

5. Go to the Advanced section at the bottom of the Firewall rule and click the drop-down box beneath to Protection.
6. Now select Microsoft RDG 2012R2

Very thankful if someone could share some light on this. I don't think it should be so hard to get this to work.
