you cannot prevent communication between clients within the same VLAN.
Can't you use a firewall for this?
Anyway, my guess is it's probably better to use a separate vlan or a DMZ for that. But given my poor security experience, others can probably better help you on this one
Seperate vlan for any external service. Fail2ban/firewalled ssh keys. All the normal stuff
Im thinking of fronting it with cloudflare and run it through tunnel eventually
Is just exposing it via a Cloudflare Zero Trust tunnel enough for security?
(Serious question that I don't know the answer to, as this is what I'm currently considering for a project.)
From what I've read about Cloudflares Zero Trust Tunnel thing it's actually more secure than hosting it with a public IP address.
To be clear I haven't done it. So idk for sure. But it sounds like they use some kinda 2fa system to get to your services, you don't expose a public IP, and it's all behind Cloudflares service. Which is great for security. If you trust Cloudflare. I trust Cloudflare, but some folks might not.
I might check this out as a weekend project tho. See how it differes from my setup with vlans, VM's, firewalls and fail2ban.
Welp, I did it. One nice thing is that Cloudflare has an official WordPress plugin that applies recommended security settings.
I will note that WordPress does not take kindly to being setup on http localhost, then put into a Cloudflare Tunnel. It goes into a redirect hell that I wasn't able to figure out. You basically need to setup the tunnel, then run the WordPress install script from scratch.
Exporting from http localhost to your URL on Cloudflare is also not fun. The import process fails at pulling in your photos. Luckily, my blog was mostly empty, so manually re-adding the media to the posts didn't kill me.
I would highly suggest using a separate VLAN at the minimum directly off your firewall, and at the ingress of your firewall put rules in blocking any traffic from the server to the rest of your home. You can always allow ssh from your work env to the server, but block unsolicited traffic from the server to your home. I’d also suggest potentially leveraging a secondary public IP if you have service that will give you a block of IP addresses for a fee. It would be worth it to just keep your home separate from any denial of service type attacks directed at your lemmy instance.
Got it, thank you. I'll look into the 2nd static IP from Comcast. That is/ was one of my major concerns. I don't want my whole home network going down if someone decides to dos it
