Hostname Configuration; Dns Configuration; Extended Configuration; Interface Control - KEMP Technologies LoadMaster 1500 Installation And Configuration Manual

Ethernet interfaces. I.e. the optional interfaces will be designated as eth0 and eth1. For more information on
this topic please contact customer support.

4.2. Hostname Configuration

The hostname of the LoadMaster can be changed. When the system is configured as a HA cluster, the
hostname 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 the
same broadcast network (Ethernet segment).

4.3. DNS configuration

This option allows the configuration of the LoadMaster name resolution facility. If no DNS parameters are
specified, 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 Configuration
This 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 the
same network as the LoadMaster.

5. Extended Configuration

This menu allows the user to configure several features, which do not directly affect the main function of the
LoadMaster but makes the balancer easier to use.

5.1. Interface Control

This option allows the configuration of the protocol used at the physical level on the Ethernet. Normally, the
LoadMaster will auto detect (auto-negotiation) which Ethernet protocol it should use. Sometimes this process
does not always work. With this option, the user may force the LoadMaster to use a specific protocol (either
100Mb 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-NAT

This 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. The
LoadMaster will use "masquerading" so that connection requests from the real servers seem to originate on
the LoadMaster. This means that the real servers can be on a private network and still have access to the
Internet.
When S-NAT is disabled, the LoadMaster will not perform "masquerading" and so the real servers cannot
access the Internet through the LoadMaster.
In Single-Armed configurations, S-NAT does not provide any extra functionality.
