6. Specifying the NetScaler 9000 system’s Mapped IP Address
The NetScaler 9000 system uses mapped IP addresses to establish
connections between itself and the web servers connected to it.
When the client sends a request (using the web server’s IP address), the
NetScaler 9000 system forwards the request to the web server using the
Mapped IP address specified in the Mapped IP Address parameter.
By default, the servers do not get the actual client IP address.
For the servers to get the actual client IP address, use the
set config
CLI command to set the client IP header information.
Note:
1. Each Mapped IP address supports up to 64,000 simultaneous
TCP connections. If your web server needs more connections,
you can specify additional mapped IP addresses, as described in
the next section.
2. In a high availability configuration, both NetScaler 9000 systems
must have the same mapped IP address.
3. Assigning a single mapped address may not be sufficient. If your
site needs to support more concurrent connections, you can
assign additional mapped IP addresses. See the section
“Specifying the Netmask” on page 32.
Enter the IP address that you want to use as the mapped IP address when the
following screen is displayed:
Mapped IP Address
-----------------
This specifies the NetScaler 9000 system’s mapped IP
address that is used by the NetScaler 9000 system to
establish connections between itself and the web servers
attached to it.
Enter the mapped IP address []:
The NetScaler 9000 system provides a default Mapped IP address that is the
next consecutive IP address after the one assigned to NetScaler 9000 system.
For example, if the NetScaler 9000 system's IP address is 10.101.2.54, then
10.101.2.55 is provided as the default Mapped IP address.
