I'm using a RPI Zero to route USB tether from my android smartphone to several devices. I need to use PDA Net to mask the tether from my carrier. I have the RPI setup with LEDE and runs as a WiFi AP just fine. The trick is getting the tether to work. As a hot spot, I have no internet access to the RPI so any additional packages will need to be downloaded on my PC, and manually installed. If anyone has any ideas it would be greatly appreciated. BTW, the smartphone is a Samsung J2 Core using Metro by T-Mobile.
I have a zero in use as AP (running Raspbian) and solved the update/upgrade problem by installing a proxy server on my PC (Squid), forward it's port using an ssh tunnel, and run apt with an environment variable:
http_proxy=http://localhost:3456 apt update
Opkg also supports the use of a proxy server. https://openwrt.org/docs/guide-user/additional-software/opkg#proxy_support
I think Im going the Raspian way. Id like more info on Squid. Also is their a version of Luci that I can run?
