Con esta herramienta que le ayuda a entonar los valores de su DNS , si lo corren tal cual como esta esta configuración podrán ver que los warning se trata por convención que debe existir otro DNS autoritativo.NOTA: la zona inversa de su IP usted no pude controlarla, su ISP tiene que crearla. (Esto es muy importante si va tener correo con este su dominio por esta IP)Hasta aquí tenemos un DNS autoritativo funcional...!!!Ahora vamos a crear otro servidor DNS autoritativo pero que sea esclavo de nuestro primer DNS autoritativo.

XML tag Description Default value elements Enable SSL VPN. Boolean value: [0 | 1] 1 FortiClient disables Windows OS DNS cache when an SSL VPN tunnel is established. The DNS cache is restored after SSL VPN tunnel is disconnected. If you observe that FSSO clients do not function correctly when an SSL VPN tunnel is up, use to control the DNS cache. 0 When this setting is 0, the custom DNS server from SSL VPN is not added to the physical interface. When this setting is 1, the custom DNS server from SSL VPN is prepended to the physical interface. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient uses the new SSL driver. When this setting is 1, FortiClient uses the legacy SSL driver. Boolean value: [0 | 1] 1 DTLS supported only by FortiClient (Windows). When this setting is 0, FortiClient uses TLS, even if dtls-tunnel is enabled on the FortiGate. When this setting is 1, FortiClient uses DTLS, if it is enabled on the FortiGate, and tunnel establishment is successful. If dtls-tunnel is disabled on the FortiGate, or tunnel establishment is not successful, FortiClient uses TLS. DTLS tunnel uses UDP instead of TCP and can increase throughput over VPN. Boolean value: [0 | 1] When this setting is 0, FortiClient allows IPv6 connection. When this setting is 1, FortiClient blocks IPv6 connection. FortiClient uses only IPv4 connectivity when the SSL VPN tunnel is up. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient creates the DHCP public server route upon tunnel establishment. When this setting is 1, FortiClient does not create the DHCP public server route upon tunnel establishment. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient registers the SSL VPN adapter's address in the Active Directory (AD) DNS server. When this setting is 1, FortiClient does not register the SSL VPN adapter's address in the AD DNS server. When this setting is 2, FortiClient registers only its own tunnel interface IP address in the AD DNS server. 0 When this setting is 0 and an invalid server certificate is used, FortiClient displays a popup that allows the user to continue with the invalid certificate. When this setting is 1 and an invalid server certificate is used, FortiClient does not display a popup and stops the connection. Boolean value: [0 | 1] 0 Retry restoring an active VPN session connection. Boolean value: [0 | 1] The XML tag may contain one or more elements. Each has the following:1 1 1 1 ⋯ - Wikipedia

11, 2021, 11:24am 5 Does your CheckMK run on a CheckMK appliance or installed on some linux server? If installed on a linux server you could install and configure a bind server on the system and use this to forward dns requests to the responsible dns servers. Wummeke December 1, 2021, 12:48pm 6 hi @uwoehler We use a Linux server for Checkmk. However, I think your suggested sollution won’t work either, since almost all DNS lookups work fine in the current situation, except for a few hosts in a specific WATO folder. I don’t see how a bind server can fix that since I think that it is just a replacement for DNS. (But I am not familiar with bind, so I could be wrong of course!) uwoehler (Udo Wöhler) December 1, 2021, 1:24pm 7 My solution of course does not change anything folder specific, but I expect that you can resolve those hostnames using another dns server and that this is probably hosting another domain. So you could use bind to send dns requests for this special dns domain to the server that can resovle it. system (system) Closed December 1, 2022, 1:25pm 8 This topic was automatically closed 365 days after the last reply.

2025-04-01Con esta herramienta que le ayuda a entonar los valores de su DNS , si lo corren tal cual como esta esta configuración podrán ver que los warning se trata por convención que debe existir otro DNS autoritativo.NOTA: la zona inversa de su IP usted no pude controlarla, su ISP tiene que crearla. (Esto es muy importante si va tener correo con este su dominio por esta IP)Hasta aquí tenemos un DNS autoritativo funcional...!!!Ahora vamos a crear otro servidor DNS autoritativo pero que sea esclavo de nuestro primer DNS autoritativo. De ahora en adelante llamaremos Master al primer DNS autoritativo instalado y al siguiente Esclavo.Lo primero que vamos hacer es ir a la NIC y al dominio adquirido agregar otro servidor DNS.

XML tag Description Default value elements Enable SSL VPN. Boolean value: [0 | 1] 1 FortiClient disables Windows OS DNS cache when an SSL VPN tunnel is established. The DNS cache is restored after SSL VPN tunnel is disconnected. If you observe that FSSO clients do not function correctly when an SSL VPN tunnel is up, use to control the DNS cache. 0 When this setting is 0, the custom DNS server from SSL VPN is not added to the physical interface. When this setting is 1, the custom DNS server from SSL VPN is prepended to the physical interface. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient uses the new SSL driver. When this setting is 1, FortiClient uses the legacy SSL driver. Boolean value: [0 | 1] 1 DTLS supported only by FortiClient (Windows). When this setting is 0, FortiClient uses TLS, even if dtls-tunnel is enabled on the FortiGate. When this setting is 1, FortiClient uses DTLS, if it is enabled on the FortiGate, and tunnel establishment is successful. If dtls-tunnel is disabled on the FortiGate, or tunnel establishment is not successful, FortiClient uses TLS. DTLS tunnel uses UDP instead of TCP and can increase throughput over VPN. Boolean value: [0 | 1] When this setting is 0, FortiClient allows IPv6 connection. When this setting is 1, FortiClient blocks IPv6 connection. FortiClient uses only IPv4 connectivity when the SSL VPN tunnel is up. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient creates the DHCP public server route upon tunnel establishment. When this setting is 1, FortiClient does not create the DHCP public server route upon tunnel establishment. Boolean value: [0 | 1] 0 When this setting is 0, FortiClient registers the SSL VPN adapter's address in the Active Directory (AD) DNS server. When this setting is 1, FortiClient does not register the SSL VPN adapter's address in the AD DNS server. When this setting is 2, FortiClient registers only its own tunnel interface IP address in the AD DNS server. 0 When this setting is 0 and an invalid server certificate is used, FortiClient displays a popup that allows the user to continue with the invalid certificate. When this setting is 1 and an invalid server certificate is used, FortiClient does not display a popup and stops the connection. Boolean value: [0 | 1] 0 Retry restoring an active VPN session connection. Boolean value: [0 | 1] The XML tag may contain one or more elements. Each has the following:

Votre appareil utilisera désormais votre paramètre de serveur DNS primaire (DNS 1) lorsque vous serez connecté à ce réseau Wi-Fi.Notez que l’étape ci-dessus change les paramètres DNS uniquement pour l’appareil sur lequel vous faites la modification. Pour configurer votre serveur DNS préféré sur l’ensemble de votre réseau domestique, il est préférable de changer les paramètres DNS à la source. Tous les appareils qui y sont connectés appliqueront le nouveau protocole.Comment modifier vos paramètres DNS sur un routeurVous pouvez modifier les paramètres DNS de votre routeur à l'aide de son interface web. La procédure varie légèrement en fonction du routeur que vous utilisez. Pour modifier les paramètres DNS de votre routeur, vous devez lui attribuer une adresse IP statique. Consultez le guide de l’utilisateur ou le manuel d’installation pour en savoir plus.Voici comment changer de serveur DNS sur les routeurs les plus courants.Routeurs LinksysSaisissez dans la barre d'adresse de votre navigateur et connectez-vous à l'interface web de votre routeur Linksys.Cliquez sur Setup (Configuration) dans le menu principal, puis sélectionnez Basic Setup (Configuration de base).Indiquez vos serveurs DNS primaire et secondaire préférés dans les champs Static DNS 1 (DNS 1 Statique) et Static DNS 2 (DNS 2 Statique).Vous pouvez ajouter le serveur DNS primaire d’un
