it's impressive to me too since it's free: i used to use the vpn feature heavily when showing up to work in the office was still a thing for me.
i still use the ssh server with sshfs as a cloud-like storage for uploading things from my phone and work computers like pics and for downloading media like music and videos; although i've been gradually weaning myself off that via social media content so that now i barely use it at all besides as an ssh tunnel.
the add blocking alone makes the effort worth while for me and i've gotten so used to it that i can no longer tolerate adds when i have to to use other people's rigs; it's makes me strangely angry somehow. lol
i created this post about how i have it setup; but this time around i'm going to replace the windows vm behind the pfsense vm with a physical AP since that's the part of the stack that's the most proned to breaking. i'm not to enthused about doing so because i have a high gain antennae attached the internal wifi nic that i was using as an AP, so i got GREAT signal for really long distances and even into the underground parking lot of my apartment building and the beach nearby, but i rarely ever us it as such so it's hard justifying the headache to myself.
