I have a dynamic IPv4 address and a static IPv6 /48 prefix on my WAN interface.
Network adapter is a Mellanox ConnectX/3.
WAN config:
- Block private networks [X]
- Block bogon networks [ ] (due to default deny bogons rule blocking dhcpv6 traffic; see https://forum.opnsense.org/index.php?topic=33616.0 (https://forum.opnsense.org/index.php?topic=33616.0))
- IPv4 Configuration Type [DHCP]
- IPv6 Configuration Type [DHCPv6]
- Request only an IPv6 prefix [X]
- Prefix delegation size [48]
- all other checkboxes unticked
Every 8-10 seconds, a log entry "... configd.py[nnn]: [LogID] New IPv6 on mlxen0" is written.
The IPv6 WAN IP's for mxlen0 indeed do not change:
ifconfig mlxen0 | grep inet6
> inet6 fe80::e61d:2dff:fe1c:fe70%mlxen0 prefixlen 64 scopeid 0x9
> inet6 2a02:aaaa:bbbb:cccc:e61d:2dff:fe1c:fe70 prefixlen 64 autoconf
Hint: The IPv6 address 2a02:aaaa:bbbb:cccc:xxx shown above is
outside the static /48 prefix.
/var/etc/dhcp6c.conf and /var/etc/dhcp6c_wan.conf:
interface mlxen0 {
send ia-pd 0; # request prefix delegation
request domain-name-servers;
request domain-name;
script "/var/etc/dhcp6c_wan_script.sh"; # we'd like some nameservers please
};
This problem exists since > 1 year. Today, I exported the config, reimported it and rebooted the router, but this had no effect. Everything works fine, but I wonder what is triggering the frequent log entries. Any idea ? Thank you.
It's merely reacting to incoming router announcements.

Thank you, Franco.

FWIW I bumped into this as well (now on 21.5.7), only in my case there are now 5 configd and 7 dnsmasq log entries for every RA: https://forum.opnsense.org/index.php?topic=47469.0
