TerraMaster Forum

I am using a **TerraMaster F2-423** NAS with both **2.5 GbE interfaces connected to different networks**, currently running **TOS 7.0.427**.

When I open the **Multimedia Server** settings, I notice that multiple network interfaces are listed with the same name (screenshot attached). However, only **two of these interfaces are actually valid**, corresponding to the two physical connections.

Since the interface names appear identical, it is difficult to distinguish which entry corresponds to which network interface. As a result, I currently have to configure them one by one and test which interface the server is reachable through.

This issue appeared after I **upgraded the system from TOS 6.0 to TOS 7.0**.

Could you please advise if there is a way to clearly identify the correct interfaces or resolve the duplicate interface listing?

I don't see the duplicate lan options. (admittedly not running 0.427 on my -424 where MMserver is installed). I see a listing for LAN1, LAN2 and BOND1 - where I have the 2 lan interfaces bonded to a single network. This I accept as reasonable.
Do you by any chance have IPv6 enabled? Maybe causing listing an interface for each protocol - but that would only, logically, explain 4.
{Have you reported this as a bug by email (as per Beta protocol) to see what the development team have to say?}

Hi,

Thank you for your response.

I understand that when IPv6 is enabled, each IP interface creates a separate LAN. Since IPv6 is enabled in my setup, the presence of four LANs is expected, as you explained. However, the appearance of a fifth LAN remains unclear. Additionally, even if one LAN corresponds to IPv6 and another to IPv4, the current naming convention is somewhat confusing.

I will proceed with raising this as a bug so that it can be investigated further.

Thank you.

We have noted the situation you mentioned, and the project team will attempt to reproduce and investigate the issue based on the information you provided.

This issue has been resolved and optimized; please look forward to future updates to TOS 7 Beta.
