How mount a share folder of another OpenWrt server in my OpenWrt server?

[pharizna]

Problem solved!

OW2
/etc/export
/mnt/sda6 192.168.1.250/24(rw,sync,no_subtree_check)

OW1
mount 192.168.1.251:/mnt/sda6 /mnt/MOX

Now, I can use my Jellyfin media files from my local SSD in my NanoPi R5S or from my MOX.
