An enterprise-class firewall, like the free versions of pfSense, OPNsense, Sophos UTM, etc. These will provide better security by filtering incoming traffic. I'm no network engineer and I've been running pfSense at home for years. - Source: Reddit / 16 days ago

Install OPnsense: https://opnsense.org/ and away you go. OPNnsense will give you the power of a huge enterprise level router/switch for basically little cost besides some cheap hardware and some time. - Source: Reddit / about 1 month ago
I’d recommend OPNsense over Pfsense. The owners of Pfsense (Netgate) do not seem to understand open source at all. - Source: Reddit / 2 months ago
You might also look into OPNSense (https://opnsense.org/) which seems very similar to PFSense. I have not used it yet, but I may eventually switch to it due to some questions about PFSense remaining open source. - Source: Reddit / 2 months ago
