General Discussion / Wrong prefix delegation size
« on: September 27, 2023, 09:58:39 am »
Hello,
until last night IPv6 worked fine. After playing a bit around with CARP and IPv6, I reconfigured everything to the previous setup but now the WAN interface shows the wrong prefix delegation size (which should be 57, but it indicates a 58). Further, non of the interfaces using track interface is showing an IPv6 any more. My first question would be how to force the WAN interface to use the Prefix delegation size actually set in the [WAN] Interfaces setting?
My second more general question is the following: since my ISP rarely changes the prefix, I cannot set a CARP for virtual WAN which corresponds to a real IPv6 GUA but I would have to use someting like fe80::1 or fd00::1. Is that possible? If yes, is there any additional routing required on the side of the ISP router or any NAT in opnsense or whatsoever?
Thanks!!
