    I was originally having issue with the WAN interface flapping, but 2.2 RC has fixed that :). However when I look at my LAN DHCP System log it seems to show a never ending loop of DHCPACK and DHCPREQUEST statements. I can't complain too much since it all works just fine, but I wonder if this is the way it is supposed to look. I am using a Fit-PC2 with the NIC for the WAN and a USB Ethernet dongle for the LAN side. I haven't tried switching them to see if it's the dongle that causes the loop.

    Here' s a snippet of the stream (MAC addr changed to protect the innocent):
    Dec 14 11:19:53 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:19:53 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:12 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:12 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:19 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:19 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:28 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:28 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:44 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:44 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:56 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:20:56 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:21:14 dhcpd: DHCPREQUEST for 192.168.0.101 from ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0
    Dec 14 11:21:14 dhcpd: DHCPACK on 192.168.0.101 to ff:ff:ff:ff:ff:ff (ubuntu-desktop) via ue0

    The stream of REQUEST and ACK statements continues, but I figured this was enough.

      What's your DHCP lease length? Do all your DHCP clients show up that way or only that one?

        The lease length is set to the default of 7200 sec. I cleared the logs and all is quiet for now. I don't see it flapping yet. I'll check tomorrow and see what happened.
