I have install OpenWrt on my Nexx WT3020F and config it for share USB content by Samba (https://openwrt.org/docs/guide-user/services/nas/usb-storage-samba-webinterface).
I have connect the device to my network by WIFI, so I have set firewall to have access to LuCI by WAN.
Now I'd like set OpenWrt to share USB content (with Samba) by WAN, if I use a LAN cable to connect the device with my PC I have see the shared content by if I try to use WAN (withou LAN cable) I can see LuCI interface but not USB content.
Can you help me? (note I'm not an expert, this is my second time with OpenWRT)
