Dhcpd: unexpected ICMP Echo Reply from



  • hi folks,
    i've got a pfsense running on a dsl, 3 interfaces, 1 lan, 1 wan, 1 dmz, dhcp listening on lan and dmz. today the says this:

    dhcpd: unexpected ICMP Echo Reply from XXX.XXX.XXX.XXX (ip from inet)

    I thought, dhcp is only listening on lan and dmz-interface?!

    regards, dennis



  • @SCL:

    dhcpd: unexpected ICMP Echo Reply from XXX.XXX.XXX.XXX (ip from inet)

    It does.

    Is that IP your WAN's gateway by chance?



  • yes, it is :) what does that mean?



  • i want to know that firewall can detect the dhcp if using by wifi or hotspot not by LAN?????



  • @SCL:

    yes, it is :) what does that mean?

    It was a good hunch then.  :)

    The quality RRD graph pings your default gateway. I found some instances of people reporting dhcpd picking up echo replies other than its own (I believe it pings IPs to see if they're assigned prior to assigning a lease, but I'm not sure offhand how pfSense dhcpd is configured). dhcpd apparently detects those replies while listening for other replies, when it shouldn't. Just cosmetic though, I wouldn't worry about it.



  • thx for the explanation :)
