I currently have several VLANS (management for network devices, iot for smart devices, infra for security cameras and NAS, one for personal devices, anothe for guests, etc.
Currently I’m hosting a game server which is exposed to the outside world and am thinking of adding a couple more similar services.
Is it best practice to put such machines on their own isolated VLAN to minimize their attack surface?
Here is my quick list for outward facing servers:
Realistically speaking if you’re doing this just for a few friends why not require them to access the server through WireGuard VPN? This will reduce the risk a LOT and won’t probably impact the performance. This is a decent setup guide https://www.digitalocean.com/community/tutorials/how-to-set-up-wireguard-on-debian-11 and you might use this GUI to add/remove clients easily https://github.com/ngoduykhanh/wireguard-ui.
I really would love to know what’s the downvote about.
