Double NAT network storage issue.

I just bought a sft1200 travel router. I connect it to my main router via wan port.It works fine, including VPN, after opening the required port on my main router. But I can not find any network storages connected to the main router and nor the Google drive folder. Any suggestion?

Hello,

Please manually upgrade to the latest beta firmware v4.7.2, it supported the local USB storage share 'samba' in v4.7.2.

GL firmware does not support third-party Internet storage like google drive.
