Nakivo Backup on separate (direct) lan connection

Hello everyone,

I would like ask you for an advise.

This is only about my home lab, so just simple one esxi host without vcenter.

I am also using Nakivo as backup solution for my lab thats running on QNAP.

So far they were both on same subnet running without issues.

This week I added a 10GB connection to both devices and have just direct cable connection between them.

From esxi and VMs on top of it I can reach the QNAP without problem (NFS, SMB, SSH).

Also from QNAP itself I can SSH to the ESXi host.

All this using the 10GB connection.

But when I add this host with a new IP to Nakivo It all behaves very weird.

I know Nakivo is using ports 902 and 443, but nothing is being blocked on esxi side.

The only message I receive in hostd logs on esxi is

Accepted password for user nakivo from 192.168.168.5

I am sure there is no blocking, network is setup correctly.

The thing I am not sure about is how in general esxi works with 2 management interfaces.

I would be very glad if you have any suggestions.

BR,
