I'm experiencing a problem of no IPv6 default route on my TrueNAS CORE 13.0-U4 system. This problem has been posted on these forums a few times, but with either no resolution or a resolution that is not relevant for me. I apologize if there has been a solution that I just didn't see. Any help would be greatly appreciated, thank you in advance!
Problem Summary
TrueNAS is set up to autoconfigure IPv6. It receives router advertisements (both from rtsold and unsolicited) and autoconfigures an address in every advertised prefix, but does not configure the default route.
The system is running virtual machines, and these virtual machines do not have the same problem as the TrueNAS host. All VMs have default IPv6 routes to the internet and are able to 'ping -6' both LAN and public internet addresses.

Here are a few somewhat relevant threads that I found while looking for a solution

Details
- Version: TrueNAS CORE 13.0-U4
- Interface configuration: Physical interface em0, manually created bridge bridge0, with DHCP and Autoconfigure IPv6 selected. Three virtual machines use bridge0 as their parent interface.
- Interface bridge0 has several IPv6 addresses (ULA and two globally routable prefixes, with privacy addresses). The bridge contains members em0 and three virtual machine interfaces. ACCEPT_RTADV is set on the interface.
- rtsold is running
- Router advertisements are being received, with nonzero router lifetime
- No default ipv6 route, even though there is a default ipv4 route and IPv6 on link routes to all the advertised prefixes.
Other relevant threads
Here are a few somewhat relevant threads that I found while looking for a solution
- No default gateway found for IPv6 - original poster just wants to disable IPv6 for a resolution
- IPv6 default route - Again not working - no replies
- No IPv6 default gateway (via SLAAC) - recommendation to manually configure the bridge, which I have already done.
