+Ok so I started doing some research about hosting Gitea but went down quite the rabbit hole about network security.
+Before setting up Gitea and all that, I want to make sure I have a secure network that I really understand well.
+Some notions to check out:
+[x] port forwarding
+    [] security risks
+[] VPN (tailscale)
+[] network-level firewall (opnsense/pfSense/UDM ??)
+[x] external/internal reverse proxies (cloudflare/traefik/nginx)
+[] IDS & IPS (Intrusion Detection/Prevention System)
+[] VLANs
+[] auth proxy?
+[] managed switch
+[] pfSense router
+[] SSL certs? (certbot)
+[] SSH
