WAN and DHCP on XG-7100



  • I get a new netgate XG-7100 and i assign WAN port on lagg0.4090. I put my cable comming from my ADSL modem which is configure with a DHCP Server (working well). My wan interface don't get address. This is the log

    Did you reboot the modem?



  • yes, DHCP work well. I test it.


  • Netgate

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

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


  • Netgate

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



  • I test it with, other laptop, desktop, DHCP work well. just the netgate refuse to get an address. perhaps it is a hardware problem

    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 ?

    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.
