Wifi AP in OPT port
-
Hi,
another perhaps noob question here, but I have a Wifi router that has been converted into a wireless AP.
It has a static address on my net.
It was plugged into a switch on the lan, but I would like to isolate it into an OPT interface on the pfsense box.
I have created the interface, bridged it to the LAN, but since the AP has a fixed IP address, how do I configure
the IP configuration type in the interface to ensure clients connecting to the AP still get a DHCP address ?
If I select DHCP in the interface that should mean that the pfsense box will issue an address from the DHCP pool to the AP
not necessarily anyone connected to it…right ?
What am I not getting here?If I set it to None, then anything connecting to it is NOT getting an IP address..
thanks
Chris

If you want to isolate it what is the bridge for? That's the opposite of isolation.
Delete the bridge
Pick a new subnet for the OPT1 network
Set OPT1 to use that subnet
Put the appropriate firewall rules on OPT1 for your Wi-Fi users
Create a DHCP instance for OPT1 -
And don't use the "router" bit of "WiFi router". Ignore its "WAN" port - plug one of its LAN ports into pfSense OPT1. Disable DHCP on "WiFi router". That way it will act like just a dumb AP, and clients can get their DHCP, DNS… direct from pfSense.

Create a DHCP instance for OPT1In the Itnterface allocation tab for pfsense, when I enable the OPT interface it is looking for an IP configuration type which has DHCP, Static etc.
When you state "Pick a new subnet for the OPT1 net" how would I do that ? Sorry I'm not clear on that part. IF I want to create a DHCP instance, would I select this as an IP config type ? IF so wouldn't that conflict with my AP which already has a fixed IP address ? IF you are referring to activating the DHCP service on the OPT interface, then that is only possible if my OPT interface has a static address which I can do in the interface assignment tab, however since the AP already has a pre-canned Fixed IP, what should I do. Change the AP to DHCP ? not clear on how that works.
…and thanks very much for your insight and assistance.Chris

Choose an unused subnet from the RFC1918 space. Assign it to pfSense OPT1. Set a DHCP instance for OPT1 that serves config for that subnet.
Here are some random choices:
10.244.200.0/24
172.26.198.0/24
192.168.29.0/24Set the IP address for the LAN side of your router to a static IP on the OPT1 subnet, turn off DHCP on the AP like phil said. Plug the LAN side of your AP into the OPT1 subnet.

"Choose an unused subnet from the RFC1918 space. Assign it to pfSense OPT1"
Ok really sorry to ask this, but how and where do I assign a different subnet space to OPT1 ?
The only options on the Interface are to choose the config type. Is this done under DHCP Server
once the OPT is activated ?thanks for your patience…

You need to set a static IPv4 on OPT1.
e.g. your LAN IP might be 192.168.42.1/24
Your OPT1 IP could be 192.168.43.1/24
Then set your WiFi device management IP to something in 192.168.43.* (e.g. 192.168.43.2/24) - it is only needed so you can reach its management interface.
Then set a DHCP range on OPT1 in 192.168.43.* - e.g. 192.168.43.100-199Make sure to disable DHCP on the WiFi device.

OK thanks,
I think it has just donned on me where I am going wrong.
My Pfsense box has a small network attribution of /24 only.
I'll change that to /16.Correct me if I'm wrong, but I think this is where I went wrong.
