DNSSEC validation in resolver: Off notempty
Caution!
If DNSSEC Validation is enabled alongside Forward-Zones, it must be ensured that the domains corresponding to the forward zones can be validated within the global DNS or that they are added to the ignore domains list below. Replies corresponding to not globally registered domains are refused and lead to SERVFAIL replies for the domain in question.

When this function is activated, all DNS entries are resolved with DNSSEC without exception. This would also attempt a validation in the DNS hierarchy for only local addresses. However, due to the lack of uniqueness of the local address, it cannot be registered with higher-level DNS servers. An error message appears, the address is not resolved and the zone is therefore not accessible (using DNS).
This applies, for example, to .local domains!
Further information on the implementation of DNSSEC can be found here.
Allow DNS queries only from routed and VPN networks: On
Default
By default, only DNS queries from the following sources are answered:
  • localhost
  • local networks
  • Networks that are routed via another gateway but do not contain a default route (or shared default route)
  • VPN transfer networks or Roadwarrior address pools
Off If DNS queries are to be answered from other external networks as well, this option must be disabled

anyideas.local (Pool: Local-Pool1 If a domain is specified in the DHCP pool configuration these domains are selectable here. When a domain is selected, the DHCP hosts can be resolved either by the assigned name of the static lease or, if none is defined, by the client name with which the client registers with the DHCP server.
  • The domain is always redirected. For example, if the domain .de is configured for your DHCP pool, you will no longer be able to resolve .de domains on the internet.

  • The old values are temporarily entered under Ignore domains in DNSSEC verification, but they are marked as invalid and need to be changed
  • Dialog at login after an update
