[IPS off:]

Thanks for the hint.

IPS off:

IPS on:

I'm having a similar issue with a 18.7.4 (upgraded from 18.1.x). When switching on IPS mode, the internal interfaces immediately loose their IPv6 adresses, an the DHCPv6 fails to start. I'm seeing this log line:

dhcpd: /etc/dhcpdv6.conf line 10: expecting a parameter or declaration

Strange thing is.. that file doesn't even exist when IPS is off, but then DHCPv6 works flawlessly.

Anyone have a suggestion on this?  Maybe it's an upgrade issue?
