Allow non-domain joined computers to connect to RD Gateway on Windows server Standard 2019

Question

I have a windows server 2019, with the RD Web, and RD Gateway roles configured, I can connect to my collection from any computer joined to the same domain, but I can not connect from a computer no joined to the domain.

I do not have the option for policies neither on the RD Gateway Manager console, and when I export the properties I can see RAP is enabled. I suspect is what is blocking the connection request from non-joined computers but do not know how to modify it or disable it.

<Rap>

<Name>RDG_AllDomainComputers</Name>

<Description>All domain computers</Description>

<Enabled>1</Enabled>

<ResourceGroupType>CG</ResourceGroupType>

<ResourceGroupNames>

<ResourceGroup>ADMORTGAGE\Domain Computers</ResourceGroup>

</ResourceGroupNames>

<UserGroupNames>

<UserGroup>ADMORTGAGE\Domain Users</UserGroup>

</UserGroupNames>

Hi, Javier

Judging from the RAP configuration you provided, there are indeed limitations:

Only Domain Users (ADMORTGAGE\Domain Users) are allowed.

Only Domain Computers are allowed (ADMORTGAGE\Domain Computers)

Solution suggestions:

1. Modify the existing RAP, remove Domain Computers restrictions or add" All computers Option.
2. Or create a new RAP specifically for non-domain computers, and maintain the original policies as security protection.
