    <p>I stumbled upon your reply in my INBOX which I seldom check for
      this email account.  I don't<br>
      know which email client you're using but for Thunderbird you
      should use "Reply List".</p>
    <p>Your tcpdump of the traffic for the working client <b>is</b> on
      the same subnet as your DHCP server:<br>

      However, the two non-working clients appear to be <b>off-subnet</b>:<br>

    <p>Are you using relays?  What IP addresses does your DHCP server
      have?<br>
