It's a private network and it can be anything. Anyways, I changed to 10.x.x.x and still not able to access. You can tested on you end if you have a windows server.
I tried with ip address and still a no go. The server is in it's own domain. I see that by default Unraid is on workgroup. Every device can reach, only the server cannot. 11.0.0.0 is my LAN (pfsense).
I very new to Unraid to start off. The reason I wanted the Server to reach Unraid is for file synchronization so I can have a windows file if Unraid crashed.
I love Unraid but I need it to be able to synce data to my Windows server 2019. Yes, I can ping but unc path leads to no where. I'm on trial version at the moment.
