Hey Hans,

this is from a fresh snapshot (03.05.), firewall untouched, odhcpd loglevel 7 and your edited dslite.sh. I set WAN(4) to unmanaged and rebooted:

On a side note, for what it's worth, my provider switched me to Dual Stack yesterday (I have no idea why they are suddenly able to, but I won't protest). While DHCPv4 and v6 now work flawlessly, it seems that I can still use an AFTR to get another v4 address - I tested that with 17.01.4 - so I will still be able to deliver logs.

Thanks for taking your time and have a great weekend,

Tim
