5.3.2.1 LAN Settings
This form is used to set the general LAN settings for the LAN interface such as the IP address mode.
Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· IP Address: Default = 192.168.42.1 or DHCP client. See Default Settings .
This is the IP address of the Control Unit on LAN1. If the control unit is also acting as a DHCP server on the LAN, this
address is the starting address for the DHCP address range.
· IP Mask: Default = 255.255.255.0 or DHCP client. See Default Settings .
This is the IP subnet mask used with the IP address.
· Primary Trans. IP Address: Default = 0.0.0.0 (Disabled)
This setting is only available on control units that support a LAN2. Any incoming IP packets without a service or session
are translated to this address if set.
· RIP Mode: Default = None
Routing Information Protocol (RIP) is a method by which network routers can exchange information about device
locations and routes. Routes learnt using RIP are known as 'dynamic routes'. The system also supports 'static routes'
though its IP Route records.
· None
The LAN does not listen to or send RIP messages.
· Listen Only (Passive)
Listen to RIP-1 and RIP-2 messages in order to learn RIP routes on the network.
· RIP1
Listen to RIP-1 and RIP-2 messages and send RIP-1 responses as a sub-network broadcast.
· RIP2 Broadcast (RIP1 Compatibility)
Listen to RIP-1 and RIP-2 messages and send RIP-2 responses as a sub-network broadcast.
· RIP2 Multicast
Listen to RIP-1 and RIP-2 messages and send RIP-2 responses to the RIP-2 multicast address.
· Enable NAT: Default = Off
This setting controls whether NAT should be used for IP traffic from LAN1 to LAN2.
· Number of DHCP IP Addresses: Default = 200 or DHCP client. See Default Settings. Range = 1 to 999.
This defines the number of sequential IP addresses available for DHCP clients.
· DHCP Mode: Default = DHCP Client. See Default Settings .
This controls the control unit's DHCP mode for the LAN. When doing DHCP:
· LAN devices are allocated addresses from the bottom of the available address range upwards.
· Dial In users are allocated addresses from the top of the available range downwards.
· If the control unit is acting as a DHCP server on LAN1 and LAN2, Dial in users are allocated their address from the
LAN1 pool of addresses first.
· Server
When this option is selected, the system will act as a DHCP Server on this LAN, allocating address to other devices
on the network and to PPP Dial in users.
· Disabled
When this option is selected, the system will not use DHCP. It will not act as a DHCP server and it will not request an
IP address from a DHCP server on this LAN.
· Dial In
When this option is selected, the system will allocate DHCP addresses to PPP Dial In users only. On systems using
DHCP pools, only addresses from a pool on the same subnet as the system's own LAN address will be used.
· Client
When this option is selected, the system will request its IP Address and IP Mask from a DHCP server on the LAN.
· Advanced:
The system can be configured with a number of DHCP Pools from which it can issue IP addresses.
