Multiple DHCP subnet on one LAN interface
-
What are you thinking in terms of PF Sense? Are you going to buy an appliance or try the community version? How big is your network,did you post the majority of it or is there alot behind that.

Use VLANs. That's the normal way to have VoIP and regular stuff on the same LAN.
Unfortunately, VLAN is not a solution because many unmanaged switches in our environment do not support it.

In that case, create a 192.168.0.1 whatever/16 interface IP on LAN;
yes, but that would put them on the same subnet in practice. they could communicate with each other.

Community version only, Our network is small:
50 PC
10 VOIP DEVICE
2 proxmox server(1 backup)
11 IP CAMERA
1 NVR
5 Printer
7 switch
8 AP
8 router
max 10-20 wireless device at the same time. -
@sifti85 just by some smart switches so you can use vlans like any normal person.
You have 8 APs - but only 10 or 20 wireless on at any given time?
You may well be able to continue to leverage your dumb switches downstream of a smart one, when all the devices on a switch are in the same vlan.
So in theory depending on your layout and connections you might be going through all this nonsense when a $20-40 smart switch could remove the nonsense of running multiple layer 3 on the same layer 2. Or maybe a couple of them?
Can you draw out your network showing where your switches are, and what devices are where.
8 router
That insane no small network like that would have need of 8 routers.. Are you calling your routers AP? And doubling the count?

ye routers function as an AP. and mostly several computers and printers are plugged into them.

@sifti85 so you have 8 APs then.. If they are not doing the router function of your typical soho wifi router, then they are just APs
Nothing wrong with doing that if that is what you have to work with.. If they are running 3rd party firmware like dd-wrt or openwrt they may very well support vlans and you might be able to just leverage them as your smart switches to allow for vlans on your network.
A diagram showing how everything is connected and what devices are on what L3 ip space.. It may be possible to segment your network correctly without having to purchase anything.
But again you do not need some Cisco enterprise $$$ switches do vlans - there are plenty of 20 to 40 dollar switches on the market that understand vlans.

Tomorrow i will do it.

with zeroshell firewall I can create as many subnets on the native VLAN as I want :D how is this possible?

@sifti85 you can do whatever you want - don't make it right, running multiple layer 3 Ip ranges on the same layer 2 is just nonsense.
