If you manage to enter
IPv6 DNS address
via LuCI (!)
into file /etc/config/network
config interface ‘lan’
then Foris will complain:
jsonschema.exceptions.ValidationError: ‘2001:67c:28a4::’ is not a ‘ipv4’
which is obvious
Refers to: Foris chapter “LAN”. OS4beta1.
This appeared in 3.11 as far as I remember. But:
Who told Foris in OS4beta1 there is always v4 expected in year 2019?
Support Ticket Opened [#004283]
LuCI kills Foris for using IPv6 … bad girl!
