Configuring DS-Lite Static Maps
The NetScaler appliance supports manual creation of DS-Lite LSN mappings, which contain the mapping between the following information:
-
Subscriber’s IP address and port, and IPv6 address of B4 device or component
-
NAT IP address and port
Static DS-Lite LSN mappings are useful in cases where you want to ensure that the connections initiated to a NAT IP address and port map to the subscriber IP address and port through the specified B4 device (for example, web servers located in the internal network).
Note: This feature is supported in release 11.0 build 64.x and later.
To create a DS-Lite static LSN mapping by using the command line
At the command prompt, type:
add lsn static <name> <transportprotocol> <subscrIP> <subscrPort> [-td <positive_integer>] [-network6 <B4_ADDR>] [<natIP> [<natPort>]] [-destIP<ip_addr> [-dsttd <positive_integer>]]
show lsn static

Parameter Descriptions
add lsn static
- name
Name for the LSN static mapping entry. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the LSN group is created. The following requirement applies only to the CLI: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, “ds-lite lsn static1” or ‘ds-lite lsn static1’). This is a mandatory argument. Maximum Length: 127
- transportprotocol
Protocol for the DS-Lite LSN mapping entry.
- subscrIP
IPv4 address of a subscriber for the DS-Lite LSN mapping entry.
- subscrPort
Port of the subscriber for the DS-Lite LSN mapping entry.
- Network6
IPv6 address of the B4 device or component.
- td
ID of the traffic domain to which the B4 device belongs. The IPv6 address of the B4 device is specified in the network6 paramter. If you do not specify an ID, the B4 device is assumed to be a part of the default traffic domain.
- natIP
IPv4 address, already existing on the NetScaler appliance as type LSN, to be used as NAT IP address for this mapping entry.
- natPort
NAT port for this DS-Lite LSN mapping entry.
- destIP
Destination IP address for the DS-Lite LSN mapping entry.
- dsttd
ID of the traffic domain through which the destination IP address for this DS-Lite LSN mapping entry is reachable from the NetScaler appliance. If you do not specify an ID, the destination IP address is assumed to be reachable through the default traffic domain, which has an ID of 0.
To create a DS-Lite static LSN mapping by using the configuration utility
Navigate to System > Large Scale NAT > Static, and add a new DS-Lite static LSN mapping.
