I just noticed that on the interfaces-overview page - wan the virtual ip's of IPv4 are not showing there under the main wan IP (under IPv4 address), where the virtual ip's of IPv6 are still all mentioned as used to be (IPv6 address).
It looks like the virtual ipv4 virtual ip's are gone on this overview. The virtual ip's are working perfect, so it is a cosmetic bug. Others have this issue also?
p.s. I used this https://forum.opnsense.org/index.php?topic=21207.0 (https://forum.opnsense.org/index.php?topic=21207.0) as my interface setup PPPoE
