      briefly:
      two subnets -> no bridging.
      two subnets -> routing+firewalling(if needed)

        Thanks Eugene. I believe I have this working now. I'm still running into one issue. I have DHCP set up on the LAN interface. I want it to give IP addresses to the machines on the LAN network which it is doing correctly. My problem is that it's passing DHCP addresses over to the machines on the OPT1 network. Is there any way to stop this from happening?  I already have a DHCP server set up on the OPT1 network. Thanks again!

          Sorry, what do you mean?

            I have two networks, LAN = 192.168.1.0 /24 and OPT1 = 10.10.10.0 /24.  I have DHCP setup on the LAN interface of pfsense. I have an DHCP server set up for my OPT1 network that is separate of pfsense.  The issue I am running into is that the DHCP server I setup on the LAN interface is giving out IP addresses to my 10.10.10.0 /24 network. I would like it to only give IP addresses to the LAN network. I am trying to accomplish where I have two separate networks that are able to pass traffic between the two. I would like to keep the subnets separate though and not have the LAN dhcp server passing ip addresses across the two networks. I hope that clarifies. If not please let me know. Thanks.

              Disable the DHCP server on the OPT1 interface.

                Thanks Cry Havok. In my current setup I only have DHCP enabled on the LAN interface. It is still passing ip addresses to the OPT1 network.

                  It's impossible. You do not use brindging, right?

                    I turned bridging off on both the LAN and OPT1 interface. I am able to pass traffic between the interfaces which was my goal. My other goal was DHCP on just the LAN interface.

                      You have something else handing out DHCP leases on that network then (assuming you applied the change when you disabled DHCP on the OPT1 interface).

                      Does ipconfig/all show the pfSense host as the DHCP server for clients on the OPT1 network?

                        It seems as though after a reboot of the pfsense server everything is working correctly now. I am not receiving IP addresses on the OPT1 network and am able to pass traffic between the two networks. Thanks for all the great help…it's greatly appreciated.
