For more information onthis topic please contact customer support.4.2. Hostname ConfigurationThe hostname of the LoadMaster can be changed. When the system is configured as a HA cluster, thehostname of the partner LoadMaster can also be changed.Hint: It is not required to change the name of the LoadMaster unless there are multiple HA clusters on thesame broadcast network (Ethernet segment).4.3. DNS configurationThis option allows the configuration of the LoadMaster name resolution facility. If no DNS parameters arespecified, the administration of the LoadMaster must be performed using “dotted quad” addressing only.This option allows the configuration of up to three DNS server addresses. These must be in “dotted quad”format.Up to 6 search domains may also be specified.4.4 Routing ConfigurationThis option permits the configuration of default and static routes.The LoadMaster requires a default gateway through which it can communicate with the Internet. See the“Application Guide” section for more information on this subject.Other routes can also be specified using this menu. These routes are static and the gateways must be on thesame network as the LoadMaster.5. Extended ConfigurationThis menu allows the user to configure several features, which do not directly affect the main function of theLoadMaster but makes the balancer easier to use.5.1. Interface ControlThis option allows the configuration of the protocol used at the physical level on the Ethernet. Normally, theLoadMaster will auto detect (auto-negotiation) which Ethernet protocol it should use. Sometimes this processdoes not always work. With this option, the user may force the LoadMaster to use a specific protocol (either100Mb Full or Half Duplex).Note: If the LoadMaster is connected to a 10Mbit switch, then auto detect MUST be used.5.2. Enable/Disable S-NATThis toggle option will either enable or disable the S-NAT functionality of the LoadMaster.When S-NAT is enabled, the real servers can access the Internet using the LoadMaster as a gateway. TheLoadMaster will use “masquerading” so that connection requests from the real servers seem to originate onthe LoadMaster. This means that the real servers can be on a private network and still have access to theInternet.When S-NAT is disabled, the LoadMaster will not perform “masquerading” and so the real servers cannotaccess the Internet through the LoadMaster.In Single-Armed configurations, S-NAT does not provide any extra functionality. |
