Yes, but; Consumer routers all have security holes that can be exploited even when you do everything correctly like you did. https://www.cvedetails.com/vulnerability-list/vendor_id-11936/Tp-link.html https://www.cvedetails.com/vulnerability-list/vendor_id-1193... Looking at this one: TP-Link TL-WR940N is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the ipAddrDispose function. By sending specially crafted ICMP echo request packets, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges. Your only safe(ish) bet is to build your own, and hope that Linux/BSD close all the exploits that get discovered.
