Hello,
Not entirely sure what a cloudhost server in this concept is, but here this is how it does work.
1. domain controller = AD server computer with IP address 10.0.0.1 and name dc-01.yourdomain.com / DNS = 10.0.0.1
2. Dynamics NAV server = member server computer with IP 10.0.0.2 and name nst-02.yourdomain.com / Default Gateway = 10.0.0.1
3. Client PC = member computer with 10.0.0.3 and name client-03.yourdomain.com / Default Gateway = 10.0.0.1
WinClients connect to nst-02.yourdomain.com or via 10.0.0.2 in their clientusersettings.config file via WinClient or in their navsettings.json file via WebClient.
Thanks.
