Eine Anleitung dazu findet sich in https://forum.opnsense.org/index.php?topic=17853.0.
UDP Port 5678 = MikroTik Neighbor Discovery protocol.

Works fine here (24.7.1; Mellanox ConnectX-3; Supermicro M11SDV-8CT-LN4F).

Thank you, Franco.

Cheers

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)
• 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:

Code Select Expand


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:

Code Select Expand


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.

Same problem here upgrading from 20.7.3 to 20.7.4 (last line also "Reloading template OPNsense/xxxx").
Logged in via ssh, selected "6) Reboot system". After reboot and logging in via ssh again, I selected "12) Update from console". After that, the upgrade ran fine without further problems.

I have the same problem, and it also started with 19.1.8 (never seen before),

Similar problem here. My OPNsense has several network zones; resolving the router ip via nslookup/dig delivers all router ip addresses of all interfaces.

Go to "System" - "Trust" - "Certificates", then click on "add or import certificate". Copy+Paste certificate and private key in the empty fields, give your certificate a name and save.
Then go to "System" - "Settings" - "Administration". The Listbox under "SSL certificate" should now show your imported certificate. Select and save.
