ipv6 only failover wan network interface stops routing
I have a firewalla gold plus running 1.981 with two wan links:
- Quantum which is IPv4 only as primary. ipv6 is disabled
- Xfinity which is IPv4 and v6 as failover, ipv6 is enabled
Immediately after restarting my device I am able to connect externally via any device on the network to v6 sites:

PING6(56=40+8+8 bytes) 2601:282:1c02:5861:cdd0:eb9b:d798:c8f1 --> 2607:f8b0:400f:802::200e

16 bytes from 2607:f8b0:400f:802::200e, icmp_seq=3 hlim=115 time=12.521 ms
However, after "a while" ipv6 stops working fully:

^C
--- google.com ping6 statistics ---
19 packets transmitted, 0 packets received, 100.0% packet loss
Rebooting the firewalla resolves this issue. Also if I change a device to route all prefer the xfinity network for all traffic v6 works perfectly

Correct quantum is the primary and I don't see any outages in the interface since the prior reboot. This seems to happen after a "few days" but I have just created an hourly check script which will check and pull information from the firewalla and will update when I next detect the issue
