Dns forwarder fortigate. In your scenario when u have a fortigate 100 D firewall why are u pointing forwarders to dns the best practice is terminate both networks on fortigate and create lan on lan add your local DNS and the interface with DNS round robins so the external dns request will go through the fortigate which will scan the network packets reaching to your network over internet. I don't want to point the dns for the fortigate to the dns server at the branch office in case there is a outage that breaks the VPN connection I created a dns server on the fortigate and added the AD dns domain as a slave, pulling the zone information from the AD DNS server using this article as a guide. A Domain Name System (DNS) server implements the protocol In simple terms, it acts as a phone book for the Internet A DNS server matches domain names with the computer IP address This enables you to use readable locations, such as fortinetcom when browsing the Internet FortiOS supports DNS configuration for both IPv4 and IPv6 addressing.

To configure DNS translation in the GUI Go to Security Profiles > DNS Filter and edit or create a DNS Filter profile Enable DNS Translation and click Create New Enter the Original Destination (the domain's original IP address), the Translated Destination IP address, and the Network Mask, and set Status to Enable.

For example, if our FortiGate has a LAN IP of We would like to make as the primary DNS server in our DHCP options for our clients on this LAN, then have the FortiGate forward the DNS queries to a public DNS server and respond the client with the results This is a typical setup and scenario on most consumer/home firewalls. Michael7953 wrote We have a fortigate 0d using as the primary and our Active directory DNS server as secondary My question is should I be setup this way because on the AD servers DNS the forwarder is listed is well as 44. To specify the Azure DNS server Open the virtual network you just created Click DNS servers to open the DNS servers pane Enter the IP address of the DNS server and click Save To configure the Azure virtual network gateway In the portal dashboard, go to New Search for Virtual Network Gateway and click it to open the Virtual network gateway.

DNS forwarding is the process by which particular sets of DNS queries are handled by a designated server, rather than being handled by the initial server contacted by the client Usually, all DNS servers that handle address resolution within the network are configured to forward requests for addresses that are outside the network to a dedicated. For example, if our FortiGate has a LAN IP of We would like to make as the primary DNS server in our DHCP options for our clients on this LAN, then have the FortiGate forward the DNS queries to a public DNS server and respond the client with the results This is a typical setup and scenario on most consumer/home firewalls.

A forwarder accumulates external DNS information in its cache as it resolves DNS queries To configure the Citrix ADC appliance as a forwarder, you must add an external name server The Citrix ADC appliance allows you to add external name servers to which it can forward the name resolution queries that cannot be resolved locally. In version 62 and later, FortiGate as a DNS server also supports TLS connections to a DNS client See DNS over TLS for details By default, DNS server options are not available in the FortiGate GUI To enable DNS server options in the GUI Go to System > Feature Visibility Enable DNS Database in the Additional Features section Click Apply. Basic DNS queries are configured on interfaces that connect to the Internet When a web site is requested, for example, the FortiGate unit will look to the configured DNS servers to provide the IP address to know which server to contact to complete the transaction DNS server addresses are configured by going to System > Network > DNS Here you specify the DNS server addresses.

(1) Make sure to set DNS server properly when configuring SSL or IPsec VPN In this example a server abcdlocal which resolves to will be used (2) Make sure that you are able to ping using IP address, ping (3) Confirm whether you are able to ping using FQDN, ping serverabcdlocal. Set internal interface as dns forwarder (on ) for the client Hi all In my environment i want to configure the same ip for gateway and dns on all the clients The ip is the internal interface ip My internal interface ip is , how can i configure the firewall in the way that all the dns queries made by the clients on will be forwarded to ?.

Change your DNS Forwarders to the Fortigate or Fortiguard DNS servers This is beyond the scope of this post, but here is a good link STEP 3 Create a policy that permits the DNS servers accessing the DNS servers at Fortiguard Labs If you are going to use the Fortigate as the recursive DNS then you do not need this piece. The router will forward the packet to the Fortigate via (5) to The Fortigate will enter the session coming from its port 3 When the packet comes back, the Fortigate will look at the packet and since it has a better route via its static route (cost of 10), the packet will be out of state and considered to have failed the RPF. (1) Make sure to set DNS server properly when configuring SSL or IPsec VPN In this example a server abcdlocal which resolves to will be used (2) Make sure that you are able to ping using IP address, ping (3) Confirm whether you are able to ping using FQDN, ping serverabcdlocal.

To configure FortiGate using the CLI Set up a forwarder for the DNS database In this example, an IP address of is used to resolve the domain fortinetcom config system dnsdatabase edit “corp” set domain “fortinetcom” set authoritative disable set forwarder “” next Set up a listening interface. You can You can run the DNS Server functionality on the FortiGate and provide local lookups for the devices within (they would have to use the FortiGate as the DNS server OR their DNS servers would have to look at the FortiGate for forwarding purposes) Most organizations utilize their Active Directory DNS and have a zone for the local items. Step 1 – Convert the Fortigate into a recursive DNS Server or use the FortiGuard Servers as your forwarders Step 2 – Change your DC (DNS) Servers to forward request to the Fortigate (or FortiGuard Servers) instead of the Root Servers or any other server that might be configured Step 3 – Create a policy permitting the Internet DC (DNS) servers to query the Fortigate and/or Fortiguard DNS Servers.

Go to the Zone Transfers tab and select 'Allow zone transfers' and 'To any server' Select 'Notify' and pick 'The following servers' Add the FortiGate's IP address Select 'Ok', and select 'Ok' again On the FortiGate Go to System > Config > Features, select show more and turn on DNS Database (select 'Apply'). I also set the "forwarder" to this address, and the "sourceip" to the local address of the Fortigate, via the CLI Whenever I send requests to the Fortigate from a computer, to look up a host on the domain, I always receive NXDOMAIN no matter what.

Add a DNS Service;. The FortiGate uses DNS for several of its functions, including communication with FortiGuard, sending email alerts, and URL blocking (using FQDN) Solution Prior to FortiOS 30 MR6, DNS troubleshooting was performed via the haproxy command. Forwarder DNS en FortiGate FortiGate se puede configurar como un servidor de DNS, pero en alguna ocasión nos puede interesar que las consultas a un determinado dominio DNS, se reenvíen a otro servidor de DNS Por ejemplo, podemos configurar el Fortigate como servidor de DNS de nuestros usuarios, de forma que todas las consultas a nombres.

Lastly, with Windows AD, a common and necessary record type is a SRV record, something FortiGate doesn’t understand In order to resolve these with the FortiGate as the DNS server a forwarder has to be specified on the dnsdatabase configured on the FortiGate, this is done from the CLI as follows config system dnsdatabase. Split DNS I read somewhere in order to use Web Filter, I need to use FortiGuard DNS Let say I have internal dns which host all internal server hostname I want Fortigate which use default fortiguard dns able to solve internal server name I came with idea to do split dns OPTION1set Fortigate DNS to Internal DNS set Internal DNS forwarder to FortiGuard DNS OPTION2set Fortigate DNS to default.

The xxxx is the DNS UDP packet size that your firewall or forwarder will support, assuming EDNS0 has not been disabled on the DNS server If it's under 512, then that DNS doesn't support it, or the firewall doesn't support it and is blocking EDNS0 or the Forwarder you are using is blocking or not allowing/configured to use EDNS0. Properties > Zone Transfers. By default, FortiGate runs in forwardonly mode By setting this to recursive, it makes the local DNS database available for splitbrain functionality or forwarder retargeting Note Changing the mode is initially a CLIonly option Once you set it though, the option becomes available in the GUI (as of FortiOS 565) The “DNS Servers” menu becomes visible when enabling DNS Database in Feature Visibility Here you can see the options greyed out.
