Description
After installing 22.05.b.20220531.0600
, I noticed that the System / Routing
logs showed the following:
2001:db8:4407:41c:20c:29ff:feae:75dc
is the lan (ixv5) IPv6 address assigned from the tracked interface.fe80::20c:29ff:feae:75dc
is the lan (ixv5) Link-Local address.- lan (ixv5) shows DHCPv6 Server and RA disabled in the GUI. The interface has
Tracked Interface
set. - ixv0/2/3/4/6 have DHCPv6 Server and RA enabled. The interface has IPv6 static addresses.

I also noticed that some hosts behind the firewall were getting two additional IPv6 addresses assigned from lan (ixv5), on top of the correct IPv6 address leased by the DHCPv6 Server. I rebooted the firewall and the issue persisted. I then re-saved the DHCPv6 Server and Router Advertisements config for ixv5
, and the issue was resolved.
I ran a diff on the config.xml
file before and after the issue was resolved, and noticed that the difference was that the file contained an entry under dhcpdv6
for lan
(ixv5) with <ramode>disabled</ramode>
included. When I was experiencing the issue, the file did not contain any entry for lan
under dhcpdv6
.
