Assigned Interface (OPT1) DHCP not working correctly



  • I am a networking beginner and new to Pfsense.  I am using a PC with an Intel quad port NIC. Here is my setup…

    WAN <----- ISP Modem
    LAN <----- 4 port Switch <------ PC,Printer, TV, Laptop
    OPT1 <----- AP

    The problem that I am having is with the DHCP for an Access Point that I have assigned to OPT1.
    Under OPT1 general configuration, I have the IPv4 Config Type set to DHCP. Everything else is left at default settings.

    In the Dashboard i can see that there is an uplink connection from the AP on that port (OPT1), but it doesnt get assigned an IP address. it doesnt matter if i connect another device like a laptop to that port, no IP Address. all I get is 0.0.0.0
    Can someone tell me what I am doing wrong or if my settings are incorrect?

    Many Thanks,
    Chronicvader



  • Did you set a fixed IP to your AP? If yes check it is in the same subnet of OPT1. Otherwise set your AP to get IP from DHCP (set in OPT1).

    I have a similar configuration.

    WAN -> ADSL Modem
    LAN -> PC and trusted Wired Clients
    VPN -> NAS, Media Players
    AP -> Guest Clients, iPads, iPhones ect etc.

    AP is on 192.168.2.0/24 and DHCP assign from 192.168.2.50 to .70, I also configured static lease. The AP, a Netgear R7000 has a fixed ip (192.168.2.2) and has NAT/DHCP disabled (factory AP Mode).

    Under OPT1 general configuration, I have the IPv4 Config Type set to DHCP. Everything else is left at default settings.

    You are telling pfSense to obtain an address for the OPT1 interface from a DHCP server. What DHCP server is that?

    One typically sets a static IP address on a router interface and enables a DHCP server on the same.
