Best practice for external facing service (lemmy.world)

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.

A second IP on the same connection and router will not prevent the other IP from being affected by a ddos. A ddos is meant to either saturate a connection or overload a device. Since you will be using the same connection and device, a second IP will not help with this.

Turns out I don't have access to a second IP anyways; Only available for Businesses from my ISP :( thank you for the reply
