I’m very new to home networking. I’m not new to computers (hardware or software) - but for whatever reason, anything network-related has always been an enigma to me.
That said - I just got a new (to me) server. It’s a beefy one (made a post about it in another community). And so I figured why not just start playing around with Proxmox, learning some new things and spinning up a bunch of random VMs and whatnot.
I figured the first step would be to set up something such that I can connect to my computers from anywhere - and I’ve already done so. For that, I used Tailscale. But my question, I suppose, is now that my computers are on the internet (as in, for real on the internet, through Tailscale) - are there security precautions I have to take now and things I need to be more concerned about? Do I have to set up my own special firewall to make sure I don’t get hacked or something? I am honestly pretty clueless in that whole domain. So… ELI5 what I have to do, security-wise. Any and all help is welcomed and appreciated.
Bonus question: beefy server is beefy (yes yes, lots of power consumption, I’ve already come to terms with it. About 200W idle and should run me ~$40/mo.). Dual 18-core E5-2699 v3s. 768GB of RAM. More SSD storage in both boot drives and storage drives than the average human would use in a thousand years (SAS, SATA, & NVMe). I asked this over on c/piracy - what should I do with it? I’ve put Proxmox on it, and as said above, plan on learning things about VM hosting and different operating systems and whatnot. I’m also planning on hosting my own Jellyfin server. But… what else? Does anyone have any good ideas for any (non-GPU-intensive) things I can do with the server? Anything and everything welcome, lol - I wanna have fun with this thing!
I found tteck’s Proxmox Helper Scripts great for getting my proxmox experience off the ground. I’m similar to you with just recently getting started while having limited network experience.
I also just set up Twingate for external access following a networkchuck video and love how easy it was. I was just going to do a vpn on my unifi router but this was a more streamlined solution.
As far as services, I’ve got:
Plex
Home Assistant (a huge but fantastic rabbit hole)
pihole
A docker LXC running Portainer, a transmission+OpenVPN container, SearXNG, and Twingate
Trilium (notes app similar to Evernote or OneNote)
Nextcloud (kind of frustrated with this one, mobile auto-upload doesn’t want to ever work properly)
BlueIris NVR
Heimdall dashboard
I don’t watch enough TV to justify setting up the *arr services and prefer to find my own Linux ISOs if I’m interested in a particular one. Otherwise I’m quite happy with my setup, all running on an old desktop PC.
