Problems w/ IPv6 / IPv4

[velvet]

Hi,

I have problems with IPv6. after a reboot I sometimes have no network - neither with v6 nor with v4. I don't get a v6 prefix and the dhcpv6 daemon process is stopped! a restart does not work - crashes again and again. only deactivating IPv6 on the WAN interface and a restart helps to get v4 going! a reboot of the fritzbox and OPNsense brings v6 and v4 to run again!

SETUP:
--------

WAN -> DS-Lite
   |
Fritzbox - 192.168.178.1/24
   |
OPNsense - 192.168.178.254/24 IPv6 PD /60 at WAN Interface
  |
LAN - 172.16.16.0/24

Please update to 21.1.1 and check if the problem still exists.

[velvet]

the problem is after the update to 20.1.1. and the final reboot occurred again

UPDATE: if I reactivate v6 after the reboot, v4 and v6 work again!

UPDATE II: I have now installed the Realtek driver - now the problem seems to be fixed! :)
