        My router is in the bridge mode therefore acts like an AP. The  pfSense is being used as DHCP server on the LAN NIC. I've used DHCP on the AP to obtain IP Addresses.
        LAN IP/Default Gateway - 192.168.1.1/24
        DHCP Lease Range - .200 - .254.
        Then my ESXI is directly plugged into AP as that's the only way I can access ESXI server on LAN due to no Internet access and don't have a switch.
        I'll eventually move it to separate NIC once I figure to get network access and make devices on different networks/NICS communicate with each other.

          There is something (maybe alot) I'm missing here.

          Maybe draw me a picture of this network and put here.  Network diagram.

            Now my LAN stopped getting internet access. I still however able to access WebConfig page as I'm on the LAN. The LAN is the router that is bridged. Gets IP Address, default gateway, DNS but does not get internet access.

            The first 3 rules are completely useless. The DNS one is broken is addition, since you don't allow UDP or anything else, just TCP. Ditto for the last two ones. You won't have working DNS with this, in the first place. Also, IPv6 does not work properly with ICMP blocked.

              I'll draw it tomorrow in the morning. Current or the one I'm trying to accomplish with all Nic's?
              Ill do two just in case.

              Thanks!

                Did you delete your default TCP + UDP pass all rule on the LAN?

                Thats a problem as doctornotor said.

                  So if I understood it correctly, get rid of first three and add one for UDP? I'll disable IPv6 as I'm not using it. Anything else I'm missing?

                  Thanks!

                    make your last rule TCP and UDP

                    Then get rid of your first 3 rules.

                    Yeah - I totally missed that your last rule didn't include UDP.  My bad.

                      Do you have some reason to block something? If not, what's wrong with ANY as protocol? At minimum, you DO want ICMP/ICMPv6, in addition to TCP/UDP.

                        Technicly you're right I have no reason to block anything internally in LAN, that's what I'll have my second firewall for and will place my VM's inside NAT on the Virtual pfSense.
                        I did what you guys have told me but still unable to ping even with specific interface sites lily Google and 8.8.8.8.

                          You will never be able to ping anything with ICMP not allowed…

                            Internally yes but external hosts/sites I should be able to right? At least I was able to when it was working. Still have no internet access on the bridged LAN. I'll draw a map in few hours of my network once I'll get home.
                            Thanks!

                              Sigh. Allow ICMP if you want ping to work…

                                Wow - Thats twice doctornotor said to be sure to allow ICMP and he was uncharacteristically polite about it….  I'd try allowing ICMP.

                                  I have uploaded my network diagram. Right now all I'm trying to accomplish is to just get internet access working then I'll start planning on the virtual network.
                                  I still do not have internet access, not sure what I am doing wrong. Interfaces are in up status but no internet access from either one. I've rebooted pfsense multiple times still same issue. Thanks!

                                    Which of those are you currently trying to get working?  How many 10.129.0.1 interfaces are you planning on putting on one network?

                                      I'm trying to get both working. 192.168.1.1 and 10.129.0.1 network. Hoth have same configurations but no internet access. I do not know what's blocking it.

                                        I meant which diagram.  Start piece by piece, one interface and function at a time until you're done.

                                          Plan A, first pfsense firewall. I'm not worrying about firewall inside the ESXi server yet, moving one at a time.
                                          Thanks!

                                            Where are you trying to make NAT happen?  pfSense or VM pfSense or both?
