In my experience with my ISP (Comcast in the US), I note the following:

When the lladdr changes, the modem needs to be restarted in order for
the new lladdr to be seen. If I don't restart the modem, I see the
symptoms you document.

My ISP gives out leases with a 3-day duration, so the leases renew every
day and a half.

The "random" lladdr catches my eye. But I don't know how frequently
that changes. Could it change every time the lease is renewed?

My first suggestion might be to stay with a single lladdr for a while to
see if your setup works for more than a day and a half.

Once (if) you have that working baseline, they start experimenting with
random lladdrs.
