Thanks for the guide. It works in 2026 with Huawei e3323, BerylAX v4.8.1, OpenWrt 21.02.

One piece of the instruction isn't clear above, after adding the interface (e.g., huaweimodem in my interface), you need to add the firewall zone by editing existing zones "wan", and include "huaweimodem" interface into the covered networks. See the image attached.

Thats mostly basic openwrt configuration and not specific to Huawei E3323. You can do this while creating the interface in "Firewall" tab, too.
