Hi,

So, I’ve got pfSense running on bare metal and a TP-Link Archer c9 with DD-WRT running. I’m trying to set a static ip address for my TP-Link for the WAN of 192.168.1.2 and a static LAN ip address of 192.168.1.3. Problem is, it’s not handing out ip addresses and I don’t know why, and it’s frustrating me to no end.

ISP Modem > pfSense (LAN:192.168.1.1) > TP-Link (WAN:192.168.1.2) + (LAN:192.168.1.3)

On the TP-Link configuration:
WAN Static IP 192.168.1.2
WAN Subnet 255.255.255.0
WAN Gateway 192.168.1.1

On the TP-Link configuration
LAN Static IP 192.168.1.3
LAN Subnet 255.255.255.0
LAN Gateway 192.168.1.1

DHCP Services is OFF on TP-Link
DHCP Services are ON for pfSense

When I try to connect to the TP-Link I am not getting any ip assigned via DHCP, which tells me pfSense isn’t handing out an ip address even though I have it set as the default gateway. Do I need to do anything on the pfSense side to get this working?

Thanks for reading.

Life will be easier with a managed switch !!

However failing that, I don’t think you can use the WAN port on the TPlink, just use the LAN port instead and any connected devices ought to receive an IP.

It’s been ages since I used ddwrt but I do recall there are different modes it can be in, I suppose you want a mode that is basically operating as a hub. Plus there were many are quirky settings. Best to check out the ddwrt forum if you can for the required settings in this arrangement.

I agree !!

I just dropped the cash for a TP-Link TL-SG3424P JetStream 24 Port Gigabit L2 Managed PoE on eBay just now. Time to uncomplicate my home network setup a bit lol

WAN and LAN can not both use the same subnet 192.168.1.x/24 each segment needs to be on a different subnet in order to route traffic.
