Configure the Citrix ADC appliance as a forwarder
A forwarder is a server that forwards DNS queries to DNS servers that are outside the forwarder server’s network. Queries that cannot be resolved locally are forwarded to other DNS servers. 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. To configure the Citrix ADC appliance as a forwarder, you must add the name servers to which it must forward name resolution queries. You can specify the lookup priority to specify the name service that the Citrix ADC appliance must use for name resolution.
有关如何配置Citrix ADC的信息appliance as a forwarder, seeAdd a name server (when the Citrix ADC appliance acts as a forwarder) by using the CLI.
Note:
The Citrix ADC appliance in forwarder mode supports TCP, UDP, and UDP-TCP name servers.
- If you have configured a TCP name server, then the Citrix ADC appliance sends the DNS request over TCP.
- If you have configured a UDP name server, then the Citrix ADC appliance sends the DNS request over UDP.
- If you have configured a UDP-TCP name server, then the Citrix ADC appliance sends the DNS request over UDP. However if the truncated bit is set in the DNS response, the appliance sends such DNS requests over TCP.
Add a name server
You can create a name server by specifying its IP address or by configuring an existing virtual server as the name server.
- IP address-based name server——外部名称服务器联系域name resolution. If multiple IP address-based name servers are configured on the appliance, and the local parameter is not set on any of them, incoming DNS queries are load balanced across all the name servers, in round robin fashion.
- Virtual server-based name server- A DNS virtual server configured in the Citrix ADC. For more fine-grained control on how external DNS name servers are load balanced (for example, you want a load balancing method other than round robin), do the following:
- Configure a DNS virtual server on the appliance
- Bind the external name servers as its services
- Specify the name of the virtual server in this command.
To verify the configuration, you can use theshow dns nameServer
command.
To remove a name server, at the Citrix ADC CLI, type therm dns nameServer
command followed by the IP address of the name server.
To view the details of the DNS nameserver, at the Citrix ADC CLI, type theshow dns nameServer
command followed by the IP address of the name server.
Add a name server (when the Citrix ADC appliance acts as a forwarder) by using the CLI
At the command prompt, type;
add dns nameServer (() | )
Or
add dns nameServer (( | ) [-type ]
Examples:
add dns nameServer dnsVirtualNS add dns nameServer 192.0.2.11 -type TCP add dns nameServer 192.0.2.12 -type UDP_TCP add dns nameServer 192.0.2.10 show dns nameServer 192.0.2.10 1) 192.0.2.10 - State: UP Protocol: UDP Done
Note:
If the name server type is not specified, a UDP name server is created by default. To create a name server of type TCP or UDP_TCP, you must specify the type.
When you specify the type as UDP_TCP, two name servers (one UDP name server and one TCP name server) are created for the given IP address.
Add a name server (when the Citrix ADC appliance acts as a resolver) by using the CLI
At the command prompt, type:
add dns nameServer (( [-local]) | )
Example:
add dns nameServer 10.102.9.19 -local show dns nameServer 1) 10.102.9.19 LOCAL - State: UP Protocol: UDP Done
Local- Mark the IP address as one that belongs to a local recursive DNS server on the Citrix ADC appliance. The appliance recursively resolves queries received on an IP address that is marked as being local. For recursive resolution to work, the global DNS parameter,recursion
, must also be set. If no name server is marked as being local, the appliance functions as a stub resolver and load balances the name servers.
Add a name server by using the GUI
Navigate toTraffic Management>DNS>Name Serversand create a name server.
Set DNS lookup priority
You can set the lookup priority to either DNS or WINS. This option is used in the SSL VPN mode of operation.
Set the lookup priority to DNS by using the CLI
At the command prompt, type the following commands to set the lookup priority to DNS and verify the configuration:
- set dns parameter -nameLookupPriority (DNS | WINS) - show dns parameter
Example:
> set dns parameter -nameLookupPriority DNS Done > show dns parameter . . . Name lookup priority : DNS . . . Done
Set lookup priority to DNS by using the GUI
- Navigate toTraffic Management > DNS.
- In the details pane, underSettings, clickChange DNS settings.
- In theConfigure DNS Parametersdialog box, underName Lookup Priority, select DNS or WINS, and then clickOK.
Note
If the DNS virtual server that you have configured is DOWN and if you set the
-nameLookupPriority
to DNS, the Citrix ADC does not attempt WINS lookup. Therefore, if a DNS virtual server is not configured or is disabled, set the-nameLookupPriority
to WINS.
Disable and enable name servers
The following procedure describes the steps to enable or disable an existing name server.
Enable or disable a name server by using the CLI
At the command prompt, type the following commands to enable or disable a name server and verify the configuration:
- (enable | disable) dns nameServer - show dns nameServer
Example:
> disable dns nameServer 10.102.9.19 Done > show dns nameServer 10.102.9.19 1) 10.102.9.19: LOCAL - State: OUT OF SERVICE Done
Enable or disable a name server by using the GUI
- Navigate toTraffic Management > DNS > Name Servers.
- In the details pane, select the name server that you want to enable or disable.
- ClickEnableorDisable. If a name server is enabled, theDisableoption is available. If a name server is disabled, theEnableoption is available.
