[atlas] Probe sending DHCP request, not accepting?

Thanks for the suggestion - I had seen that but didn't have the stanza
matching by client ID as I didn't think it was necessary (MAC address alone
should be sufficient, I would've thought?). I have added it now, but it
hasn't helped.

Sure. I've placed a copy of the the request/reply at
http://dl.rsx11.net/misc/atlas_probe_dhcp.txt. I've redacted the MAC
addresses (aa:bb:cc... is the MAC of the probe) but everything else is
unchanged. I don't see anything unusual - please let me know if you'd like
a copy of the raw tcpdump output. 

I also received an off-list suggestion regarding a possible duplicate IP so
I've changed the IP assigned to the probe without it making any difference.

Not sure if it makes a difference, but I do also have rtavd and DHCPv6
servers running on the same network (IPv6 connectivity to/from the probe
was working fine until this problem started).
