On my network, I have quite a few VLANS.
One for work, one for IoT devices, one for security cameras and home automation, one for Guests, etc.
I typically keep everything inward facing, with the only way to access them via my OpenVPN connection (which only can see specific services on specific VLANs).
Recently, I thought of hosting a little Lemmy instance, since I have a couple domains I’m not doing much with.
I know I can just expose that one system/NGINX proxy and the necessary ports via WAN, but is it best practice to put external facing things on their own VLANs?
I was thinking of just throwing it on my IoT VLAN, but if it were to be compromised, it would have access to other devices on that VLAN because (to my knowledge) you cannot prevent communication between clients within the same VLAN.
Yeah, the usual approach is to create a DMZ network/VLAN where you forward external traffic to, but you can’t reach anything except the internet from.
Thank you for the reply. I’ll make sure to isolate like this if I decide to host. So when people expose Jellyfin or Home assistant via NGINX, they’re usually putting those services ok their own VLAN?
