Cisco SOHO 71 - Won't take a DHCP offer

    Hello all,

    Ok, need some help on this one. I have a Cisco SOHO 71 setup for a
    customer. Previously, it was working fine with a statically assigned
    IP. They recently replaced the cable modem and wouldn't you know it,
    no connectivity. Suddenly I find out that they would prefer if the
    router was grabbin' an IP from DHCP. Fine. So I switch it to DHCP,
    it's getting an offer, but not taking it. The ISP claims they setup a
    reservation in their server which seems to be true, it's offering me
    the same IP every time but I can't get it to take. The IP that is
    being offered is the same IP I had previously assigned to the router
    statically.

    Thanks in advance,

    Gary

    Note: I do notice this in the debug - 16:10:54: Temp IP addr:
    66.206.254.108 for peer on Interface: unknown

    Here's the config on E1:

    !
    interface Ethernet1
    ip address dhcp client-id Ethernet1
    ip access-group 199 in
    ip nat outside
    ip inspect firewall out
    no cdp enable
    !

    Note: It doesn't make a difference when I take out the access-group
    and ip inspect.

    Here is the DHCP debug, it doesn't really give any error, it just
    doesn't take the offer:
