I just got an outdoor 4G Wireless router:
Hardware Version: CPF903-V5.0_LED_190711
It is working great! Only issue is that it listens on public interface port 80, which is horribly insecure. I couldn't find a way to disable that, so I was wondering to flash an OpenWrt on it.
The question: How can I do this?
So there is a page:
where it would let me upload new firmwares, ex.: https://downloads.openwrt.org/releases/18.06.5/targets/ar71xx/generic/openwrt-18.06.5-ar71xx-generic-ap147-010-squashfs-sysupgrade.bin
But it always says: "File selected is wrong,please select a new one again!"
My purpose is to have an outdoor router with 4G connection, which I can share via Wifi.
Really many thanks!
