Description
- Add IPv4 CARP address to WAN, i.e. 10.10.10.1, prefixlen /29
- Add IPv6 CARP address to WAN, i.e. 2001:db8:0:e901::2, prefixlen /64
- Save configuration, configuration works fine
- Open configuration dialog on IPv6 CARP address again, edit description (or don't edit anything at all)
- prefixlen is set to /29, although you didn't change anything
- press save
- IPv6 CARP address is now /29, which makes a directly connected /29 route on your WAN interface, blackholing all traffic to all destinations covered by this large prefix
