        You did alter the default LAN rule to set a specific gateway.  Having multiple gateways is the kind of stuff that's important to know beforehand when troubleshooting.  Why do you have multiple gateways?  Can you hack up a quickie network diagram?  This smells like an asymmetrical routing problem.

          Oops. You are correct. We did add the gateway because we needed Internet fail-over using gateway groups.

            Where exactly is pfSense in the mix?  You appear to have a firewall and two routers between all the networks.  What's what?  What happens if yo change your default LAN rule to not specify a gateway and just let it use its default?

              LAN: allow any any gateway

              If your pointing to a specific gateway, you have to make sure rules are above the rule that sends you down a gateway that allows access you want.

              So if you have lan any any going down a gateway, and you want lan to be able to get to dmz then above the rule that sends it to the gateway put a rule with dest dmz that doesn't set a gateway.

                Thank you for taking the time to look at this.

                The pfSense is the firewall icon. The icons between the pfSense and the Internet cloud are the modems.

                I have tried this without the default gateway set and still it does not work.

                  Could I be specifying the rule incorrectly. I do have a rule (without a GW) above the global rule.

                    I don't think you should be specifying a gateway since that LAN-DMZ traffic won't be going out either of them ever.  I asked this once already without reply: What kind of boxes are in the DMZ that fail to respond to ping?  Are they Windows boxes?

                      To all who have helped.

                      I just upgraded my system from 2.3.2 to 2.3.2_1 and now it seems to be working. Must have been a bug.

                          From this post I would say its working.. You have active states and traffic..

                            Well, in my experience here I have seen many, many cases where something that should work doesn't work no matter what you do… until you upgrade, reboot or reinstall (if it's a package.)
