Q: Why are some DLNA servers not discovered?

We found that the system firewall of Oculus Quest has blocked some ports, which means any application running on Oculus Quest can't send packets to these ports of any server. Unfortunately, if your server happens to bind to these ports, it will not be able to communicate with Oculus Quest.

• Known blocked ports

  • 9000

• Known influenced services

  • Twonky (default using port 9000)

Q: Should I use SMB1 or SMB2/3?

Microsoft has been asking the world to stop using the legacy SMBv1 since 2014. US-CERT also issued a security bulletin advising to disable SMBv1 and move to SMB 2.x or preferably SMB 3.x. The following documents explain why SMB1 is deprecated.

• https://blogs.technet.microsoft.com/filecab/2016/09/16/stop-using-smb1/

Since Windows10 and Samba 4.11.0 on Linux, SMB1 has been disabled by default.
