I also tried a few fixes from here as well such as removing gateways and such and all failed.

Were you trying your changes from the command line? Mucking about at that level is liable to break things or at least make it difficult to diagnose what's going on.

From my POV step 1 is to get the pfsense box to the point you can reliably access the WAN and LAN sides. Usually a fresh install is easiest tested with a PC/Laptop/whatever attached to a small switch on the LAN port. Provided you enabled DHCP in the setup (a good idea to start) you should be able to get an IP address and login to the box. From there setup a basic "enable all" rule on the LAN side and allow WAN side access to the external port (80 or whatever you changed it to) and you should at least be able to talk to the box.

Can you describe your environment in a little more detail? Does the WAN side point to the internet or just another part of your internal network? Is DHCP already running on the WAN side and/or the LAN side?
