The result of a couple of weeks deep in the world of optical networking: my O2/CETIN fiber now terminates in an SFP+ stick, not the ISP's ONT box. Turns out XGS-PON stick modules run OpenWrt inside — and I simply couldn't walk past that. I've loved OpenWrt since forever. Can't say the same about the ISP's box... who knows what's inside. 🙂 Full write-up — diagnosis, the missing-bridge-port trap, the fix: https://gist.github.com/arapov/a2019f5dac903864f36102184ff2755a #OpenWrt #XGSPON #FTTH #GPON #homelab
