Hello, I’m getting into self hosting and looking to setup a small home lab to play around with different technologies. I’m considering setting up a DMZ to keep my lab hardware separate from the rest of the network and other users. What is some of the minimal hardware required to do this on a small budget? Also what are some of the necessary security measures I should understand. One of my first projects would be to setup a small Linux box that I can ssh into remotely. Thanks.

EDIT After much reading today and great guidance from this community this is basically what i ended up doing.... Got a dell optiplex on ebay for about 55 bucks and a dual intel network card on amazon with a managed switch. If i can bridge my current router as an access point, i should be on my way! This community rocks! Lemmy is awesome!

It depends on what u wanna run, I use an old AMD A8-7600B, wich by today standards is less than a laptop cpu. But I run OpenMediaVault wich is just a NAS, so usually my cpu usage with 2 users at the same time is around %40-%60. I recommend u to use passmark as a reference, just tipe the cpu u have in mind + passmark and make thr comparison with mine so u can have an idea.

Manually set up the local IP of ur machine in the router/modem, then in the computer (so everything is failsafe), then configure the firewall (I recommended ufw) and only allow the ports that u need in the necessary protocol, nothing more. Also, to be script kiddos safe I recommend to change the ports of everything that u can, in this case SSH, I don't remember the usual port, but change it to something like 666, 999, 6666, u get the idea, if we aren't the same as every other server in existence we r gonna be safe most of the time, disable password login and use an rsa key.

And usually it isn't necessary once u set up the machine as DMZ, but sometimes it doesn't accepts the request so make sure u can access using ur celular data. Otherwise u'll need to do some port forwarding, just do it plainly 443 to 443 and the like.
