Hi

This is most likely caused by the DNS Rebinding Protection of Unbound that prevents DNS lookups that resolve to private IP Space.
While 100.102.17.10 is not "private" in the sense of RFC1918 100.64.0.0/12 is a special address range that is reserved for Carrier-grade NAT. see: https://en.wikipedia.org/wiki/Reserved_IP_addresses and https://datatracker.ietf.org/doc/html/rfc6890#section-2.2.2

If you want to configure unbound to allow it to show "private" IP responses for impfnachweis.info you can do so:
Services > Unbound DNS > General > Custom Options
Then add
server:
private-domain: impfnachweis.info


Hope this helps

EDIT: see the relevant code for unbound in opnsense: https://github.com/opnsense/core/blob/master/src/etc/inc/plugins.inc.d/unbound.inc

same here, did the update and everything started working again. Thanks for the quick solution.

We also ran into this issue on one of our opnsense instances.

Can the opnsense-revert -r 21.1.5 frr7 be run after a complete update to 21.1.6 or do we first have to downgrade the "base-system" to 21.1.5?

German - Deutsch / Verständnisfrage Dual WAN
April 30, 2021, 02:03:43 PM
Hi

Für ein bevorstehendes Dual-WAN Setup habe ich noch eine Verständnisfrage zur Dokumentation.

In der Doku zu Multi WAN steht:
QuoteTo combine Load Balancing with Failover you will have 2 or more WAN connections for Balancing purposes and 1 or more for Failover. OPNsense offers 5 tiers (Failover groups) each tier can hold multiple ISPs/WAN gateways.
https://docs.opnsense.org/manual/how-tos/multiwan.html

Heisst das um Load Balancing und Failover zu kombinieren brauche ich mind. 3 WAN Connections?

Was ich noch nicht verstanden habe, wird das Load Balancing Setup nicht automatisch zu einem Failover Setup wenn einer der beiden Links ausfällt? Oder findet beim Load Balancing kein Gateway Monitoring statt und die ausgehenden Verbindungen werden einfach 50/50 auf funktionierenden Link und toten Link aufgeteilt bei einem Ausfall?
