Putting PFSENSE box behind C6300 Router, CablelModem , Wirless Accesspoint , Switch Combo

Does anyone know of a way I can configure my pfsense box to be behind my C6300 Netgear  MODEM/Router Combo unit .
I want to use the wireless on the c6300 as well as devices plugged into it to still work by being connected to the switch or wireless and route through the pfsense firewall using the dhcp I setup on the box.

When you say the pfSense WAN port pulls only a local IP, do you mean it gets an IP address from the Netgear DHCP (e.g. 192.168.1.x) or it gets an APIPA (169.254.x.x)?

If it is getting a DHCP address from Netgear, then that is normal.  The Netgear will still have the Internet IP and will assign local IP to wireless devices and the pfSense.  Also, I am assuming that your Cisco switch is an unmanaged model.

On your pfSense web admin page, under Interfaces > WAN, is the IPv4 configuration type set to Static IPv4 or DHCP?  If it is set to DHCP, trying giving it a static IP.  In which case, change that configuration type to Static IPv4, then further down in the Static IPv4 configuration, enter the IPv4 address that connects to the Netgear, such as 192.168.1.5.  The IPv4 Upstream Gateway should be set to None.  Save the change, then click Apply changes.

Then under Interfaces, choose LAN.  The IPv4 configuration type will be Static IPv4.  Further down under Static IPv4 configuration, enter an IP address that is not on the same network as the Netgear, so say 192.168.2.1 / 24.  IPv4 Upstream Gateway will be None.  Save the change, then click Apply changes.

Next, go to Services > DHCP server.  click the LAN tab.  Check the box for enable DHCP server on LAN interface.  Specify the range for IP addresses.  The rest of the page is optional, but if you want to specify an external DNS such as the one provided by your ISP, you can specify that or you can use Google's which is 8.8.8.8 and 8.8.4.4.  Click Save at the bottom.

Now on one of your wired computers, have it obtain an IP address by DHCP, it should pick one up based on the DHCP from pfSense such as 192.168.2.2.  Check to see what IP information it gets by going to command prompt and running ipconfig /all.  The subnet would be 255.255.255.0 and gateway would be same as pfSense LAN interface (e.g. 192.168.2.1)

Hello,
So I would like to get a better understanding of your setup.  Is the WiFi something for guest users only or is it for all users?  Are any devices connected to the Netgear going to need access to devices behind the pfSense?  Do you have any switches for wired devices?  You'll need one for the wired devices to connect to the pfSense.

My WiFi experience with pfSense has been poor, and the wireless card support is still low.  Depending on your answer to my questions above, you could probably get away with keeping WiFi on the Netgear only.

This is how I would see it working so far based on the information given.

I'm trying to keep the wifi on the Netgear up and I have all wired devices on a switch connected to the Lan port on the Pfsense box.

How do I go about doing this ?  I plug the wan port into C6300 and it just pulls local IP.

I dont care about the devices on wireless being able to see the devices that are wired. I just want it to all be able to get back out to the internet.

Thanks buddy ! Turned out to be a bad gigabit card on the pfsense box that wouldn't communicate with my managed switch.
