Good evening!
Long time lurker (Yah'll have helped me with wireguard, zerotier, the switch from 19 to 21, and many other things beside. And more recently the forums here have gotten me to the point where I can connect my cellular modem)
Problem:
Succesfully connected to Cellular Internet via Modemmanager.
Can't move packets across the cellular interface.
Not even with ping -I mhi_hwip0 8.8.8.8
Details:
I have a snapshot build (no choice) running on BPI-R4.
I am aware this is not optimal, I apologize.
I have a modem, "RM520NGL-AP" on m.2 PCIE.
