OK this is my first post so I will try to include all required information ….

I have just installed pfSense on my old PC and I can't for the life of me get port forwarding working. I have spent hours on it, reading through the tutorials, reading forum posts, but unfortunately still can't get it working.

==============================================================================================================================

Network Hardware

1. Cable internet using a ISP Provided Netgear CG3000 (gutted with stupid ISP firmware)
2. pfSense Box with 3 NICs
3. Netgear GS724T 24 port gigabit switch
4. 5 port unmanaged switch to connect PCs upstairs that connects to the Netgear GS724T downstairs.
5. Workstations in the house

Very simple setup.

==============================================================================================================================

Network Config

Netgear CG3000 Router
IP:192.168.0.1
SN: 255.255.255.0

PfSense Box
WAN NIC: ale0
WAN IP: 192.168.0.10 (DHCP assigned from router)
WAN Gateway: 192.168.0.1 (router IP)
LAN NIC: em0
LAN IP: 192.168.2.254
LAN Gateway: no idea, not sure if i even need one?
LAN DHCP Server: 192.168.2.50 - 192.168.2.150
DHCP Reservations
192.168.2.190 - Workstation
192.168.2.191 - Workstation

Netgear GS724T Switch
IP: 192.168.2.250
SN: 255.255.255.0
DG: 192.168.2.254 (pfsense LAN interface)

Netgear 5 port switch upsatirs: no ip address, just dumb device i guess.

I run a cable from LAN1 port on the netgear CG3000 router to the WAN NIC (ale0) on the pfsense box.
I run a cable from the LAN NIC (em0) on the pfSense box to port 1 on the Netgear GS724T switch.
Ports 2,3,4 on the GS724T switch are connected to workstations downstairs.
Port 5 on the GS724T is running upstairs to the 5 port netgear switch, then workstations upstairs are connected into that.

Due to the gutted ISP firmware on the CG3000 router, it does not have any way to put it into bridge mode. However it does have a DMZ option.
I have enabled the DMZ option and pointed it to the WAN IP on the pfSense box (192.168.0.10).
I have no firewall rules set on the router, its basically accepting the internet and then going to the DMZ IP I have set.

It's my assumption that pointing the router to a DMZ, effectively turns the router into a modem, and all the firewall settings are done on the pfSense box?

==============================================================================================================================

Browsing the web works fine.

So for now all I'm trying to do is forward some ports to specific workstations on the LAN. But when I add the rules they never work. Also I cannot seem to ping anything from the router diagnostic's interface either. Not sure if this is due to the DMZ setting. The only IP I can ping from the router is it's own - 192.168.0.1

The firewall logs show the traffic going to the WAN IP 192.168.0.10 for the specific ports, but its getting blocked for some reason.

I'm struggling with this one so, any help would be greatly appreciated.

I couldn't attach all the screenshots in one post so I have done it in multiple

Please let me know if you need anymore information.

Cheers
