Yeah, absolutely—just patch everything you can. Start with a stateful inspection firewall, like pfSense or OPNsense, and enable the built‑in IDS/IPS. Set up strict ACLs: only allow inbound traffic on ports you actually need—SSH over 22 but only from your home IP, HTTPS 443, and maybe 80 if you host a website. Block all other inbound. Use DMZ for any public services. For internal segmentation, create VLANs for devices: separate IoT, PCs, media, and guest. Use ACLs on the router to isolate them. Enable MAC‑address filtering if you’re really obsessive, though it’s spoofable. Keep your firmware up‑to‑date—automated updates are a must. And don’t forget to run regular port scans with Nmap and check for open ports with Shodan. If you want to go full geek, set up a captive portal for guests and log everything with syslog to a remote server. Trust me, if you make the firewall the central hub and keep everything granular, you’ll keep those random scans and malware bots at bay.
