pfSense not configuring gateway via DHCP (but server is sending address)

autumnwalker

Hello,

pfSense is not configuring a gateway from my ISP when I make a DHCP request. I get an IP and subnet without issue, but the gateway remains "dynamic".

When I run tcpdump on the interface and look at the ACK I see "Gateway-IP" in the response, but it's not under an option code as I would have expected.

Any idea what is going on here? Is it possible to have pfSense configure the gateway automatically based on this response? Example is below:

[TIMESTAMP] [SERVER MAC] > [CLIENT MAC], ethertype IPv4 (0x0800), length 342: (tos 0x28, ttl 64, id 5255, offset 0, flags [none], proto UDP (17), length 328)
    [SERVER IP].67 > [CLIENT IP].68: BOOTP/DHCP, Reply, length 300, xid 0xdec0871c, Flags [none]
          Your-IP [CLIENT IP]
          Gateway-IP 10.198.0.3
          Client-Ethernet-Address [CLIENT MAC]
