Separate network for the server?

[Anejey]

Hello.

 

I'm currently using proxmox for my home server with a dozen or so things running on it. I just use my router's dhcp to hand out the ip adresses for the containers, and then I just make a reservation to make them permanent. It works, but it's awfully messy and since I'm gonna do a clean install soon I'll have to redo a good chunk of it. I also keep forgetting which ip is for what thing.

 

Essentially what I would want is to have a separate network/router/whatever to handle all my proxmox stuff, and I want to run it in a VM or a lxc container on the same server. My router currently uses 192.168.0.100 - 192.168.0.199. Is it possible to just have a separate 192.168.1.x network for my proxmox server (that i could have full control over, and would be accessible as normal)?

 

I'm pretty much a complete noob and I've only gotten this far thanks to random internet guides. I have no idea how to make this setup, or even if its possible.

 

Any help is appreciated.

Are you planning to exceed over 250 required internal IP addresses?

 

With a simple spreadsheet or even a text file, you can keep a list of what is assigned to where.

You can do this, but to do it “right” you need a router that is vlan aware, and then you have to set up vlans and firewall rules to allow traffic from vlan to vlan. 
 

You do not want to put proxmox behind its own individual router because it will then be behind its own NAT which would cause whatever services you have on it not to be able to talk to your other devices and vice versa.

 

This is possible, but you’d need to start getting learned up on vlans. Lawrence systems has a lot of YouTube videos on setting up vlans with pfsense. 
 

But, maybe a better question is why does this matter? You can usually change the DHCP pool in your router, so you can just have the router only assign from 192.168.1.1 up through 192.168.1.150 for example. Then you can manually give your server VM’s IP’s up beyond 150, which “cleans” the list up a bit since you will know all server stuff is in the 150+ range and you can put different types of services on different sets of numbers (maybe proxmox itself gets .250, streaming related stuff in the 240’s, etc).

It's just that the router is a mess currently. Just a long, long list of random devices, vms, and lxc mixed together. I don't know why but it's just bothering me. I wanted to have something completely separate, for when I move away I won't have to redo everything in a new router. Sounds like it's more trouble than worth though, so I suppose I'll just write the stuff down somewhere to keep track of it.

I’d group them together at least. Make all your server stuff be like .200 or higher.
