I’m already hosting pihole, but i know there’s so much great stuff out there! I want to find some useful things that I can get my hands on. Thanks!
Edit: Thanks all! I’ve got a lil homelab setup going now with Pihole, Jellyfin, Paperless ngx, Yacht and YT-DL. Going to be looking into it more tomorrow, this is so much fun!
Pi-hole’s not a router, just a fancy DNS server. Your network traffic doesn’t go through it, so its impact on your speeds is negligible. Since all it does is respond to DNS queries and keep logs, it also doesn’t require a lot of processing power. I used to run it on the first gen raspberry pi, and even that puny thing could easily handle the job. Your Synology box should be able to do it just fine.
