        Provide details of your LAN, and the output of ifconfig from one of the Linux boxes. If other LAN clients work then the problem is with these Ubuntu clients. If they ae the only clients on the network then your problem may be with your network config.

                        Please answer my questions if you want my help.

                        What is their gateway setting?

                        Can any of them ping the pfSense LAN address? I'm not asking if they can ping each other on LAN. I'm asking if they can ping the pfSense LAN IP address, perhaps 172.16.0.1?

                            OK then it sounds like they're configured properly. Next is firewall rules. Please post a screen of your LAN rules. You can upload images her directly. No need to link elsewhere.

                            Do you have any packages installed?

                                Those rules look good. What is WANs? A gateway group? Can you show System - Routing - Gateways and System - Routing - Gateway Groups?

                                    I don't have a multi-WAN config so I don't have much knowledge there when it comes to gateway groups. Do other networks, like HOME or SECURITY, use the same gateway group? Are there any other clients on the TOWER network? Are these Ubuntu clients static or DHCP?

                                      @KOM Home and Security Share a gateway and one WAN, Office Has its own gateway and WAN, Tower has its own Gateway and WAN. Tower is where the Ubuntu Clients are along with tons of Wireless Bridging Equipment that connects all my Employees back to the main office. We were running Windows PCs until the Microsoft Accounts got hacked for the 10th time this year.

                                              Are the Ubuntu clients actually getting IP addresses from the pfsense DHCP server? Or is your DHCP coming from somewhere else?

                                                        You seem to be missing a default route. Are there any other clients on TOWER that are working? I'm trying to narrow this down to a Ubuntu issue or a gateway groups issue.

                                                              OK, so it's a Ubuntu issue exclusively. Where did 169.254.0.0/16 come from? That's an APIPA address. If that's what you've got for IP addresses, then that means none of the cliens could get an address from the DHCP server.

                                                                                I can't see why. That's a common mask. Test it by manually setting the mask to a /24 or /16 or something.

                                                                                    I spin up Ubuntu servers all the time, both static and dynamic, and they never have any problems talking. If it's working for you then great. I suspected it might be something totally weird, but you had it with three different boxes.
