It's saddening to see that even in 2021 manufacturers still insist on rolling their own custom shitty UI on top of what is essentially Linux's iptables and iproute2 and obviously get it wrong and introduce security vulnerabilities (not to mention miss/break/restrict functionality that the aforementioned components give you for free), all while OpenWRT is around and is trivial to port especially if you're a manufacturer.
