A few of my friends experienced the glory of PiHole in my home network and asked, if I could install such a thing in their networks as well.
Which I obviously could, but none of them are interested in updating/maintaining such a device. So I would like to collect some suggestions on how to deploy such a box with (ideally) zero interaction from my side until the end of times.
My hardware platform of choice would be a cheap thin client (Futro s920 or something like that) running Ubuntu with unattended updates enabled.
Pihole itself seem to offer an auto-updater, but I’m not sure how stable that runs in the long run - maybe Docker would be better suited here?
DO NOT run a public DNS resolver. It’ll get used as part of a DNS amplification attack, and your system will be used to DDOS somebody else.
The only viable solutions here are to either have OPs friends VPN all traffic through OPs network (there might be a way to use split tunneling to reduce total traffic used, though I’m just spitballing here), to deploy hardware locally on their network, or to use a public solution. Everything else is going to be a security risk.
Thanks for the explicit mention, I should have been less vague with my “planning the security aspects” comment. I was thinking firewall rules would mitigate that, but could moot if the friends are on a dynamic lease.
VPN is a bit of a non starter since that would require installing and running a VPN client 24/7 on all devices, else you’re dropping in a site to site VPN device on the network… At that point you might as well cut out the extra complication and just run PiHole on that point.
I actually learned about public AdGuard servers in this thread! I’d definitely lean that way if I were OP (because I personally do not want to field “the internet is not working” calls in the middle of the night).
No worries, I just wanted to make very sure that the risks for #1 were properly understood.
VPN might be able to work with split tunneling, but I haven’t tried it myself. It’d probably be more complicated than it’s worth!
I’d also lean towards the public AdGuard servers in this case, for the same reason! I’m happy to field certain calls from friends and family, but I don’t want to get the “my internet isn’t working!” calls at 2am-- I get enough of those from work! 😁
