The only one I haven’t seen mentioned here that is a requirement for me is OPNsense. I’ve been using it for a couple years, and pfSense before that for a very long time. Never going back to commercial routers and their shitty / buggy / backdoored software. I highly recommend OPNsense over pfSense for the UI improvements alone, but there are other reasons to use/support OPNsense over pfSense.

On my network it handles internet firewall, internal firewall, and all routing across 5 VLANs and between two internet gateways. It does 1-1 NAT for my public IPs, inbound VPN, outbound VPN for my *arr stack, and RDNS blocklists with the data source being a script I wrote that merges from several sources and deduplicates the list. It is my internal certificate authority (I don’t miss you at all, Windows CA), DHCP for the guest wifi, and does pihole-like ad blocking via DNS for my entire network. And it does all that running in a VM with 2GB of RAM, of which it only uses about 60% on my install.

It is an incredibly powerful tool, not terribly difficult to learn, has a pretty damn good UI for FOSS, and in my opinion is a fantastic foundation for a complex home network / homelab. Unlike pfSense, which corrupted itself twice over the years I ran it, it has never let me down. And every update has been painless over the years.

1. Samba (I can move files now, sweet!)

2. Jellyfin (I can watch stuff, sweet!)

3. Qbittorrent-wireguard (for pirating copyrighted material from the internet illegally)

4. Somesuch Wireguard solution (for accessing the backend and doin stuff)

5. A proxy somewhere else

The rest is extra. This gets my usual goals completed pretty well.
