        Did you reboot the modem?

        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

            Then you'll have to look upstream to see why those DHCP discover packets are going unanswered.

              @derelict said in WAN and DHCP on XG-7100:

              I find nothing, i am thinking if it is not a hardware problem, because with static ip mode, it is working well

                If the DHCP requests are being sent and not answered, the problem is upstream. Look there.

                    Try downloading tftpd32 and setting it up as a dhcp server, does your WAN port get an IP address when its connected to the laptop ?

                    http://tftpd32.jounin.net/

                    Maybe you need to spoof the MAC address on the WAN interface.

                      Again, if the DHCP requests are going out the wire and there is no response, you need to look upstream for the reason.

                        I ran across this post when trying to figure out why a new WAN interface on my XG-7100 was not getting a DHCP address from my internet provider's router/modem. I was experiencing the same symptom, a laptop would be able to obtain an IP, but the XG-7100 would not.

                        The issue was that the new VLAN group I setup (under Interfaces -> Switch -> VLAN) did not have the ports 9 and 10 added as tagged members to the new group. Once I added the tagged ports 9 and 10, the new WAN was able to obtain an IP.

                        My headache really boils down to a case of RTFM. The online document: https://docs.netgate.com/pfsense/en/latest/solutions/xg-7100/switch-overview.html was really helpful in my case.

                        I hope this helps someone else avoid hours of head scratching.
