Configuring the Global NetExtender IP Address Range

The NetExtender > Client Settings page allows the administrator to specify the global client address range. The address range can be specified for both IPv4 and IPv6. An IPv6 address pool for NetExtender is optional, while an IPv4 address pool is required. The global NetExtender IP range defines the IP address pool from which addresses will be assigned to remote users during NetExtender sessions. The range needs to be large enough to accommodate the maximum number of concurrent NetExtender users you wish to support plus one (for example, the range for 15 users requires 16 addresses, such as 192.168.200.100 to 192.168.200.115).

The range should fall within the same subnet as the interface to which the SRA appliance is connected, and in cases where there are other hosts on the same segment as the SRA appliance, it must not overlap or collide with any assigned addresses. You can determine the correct subnet in one of the following ways:

•
You may leave the NetExtender range at the default (192.168.200.100 to 192.168.200.200).
•
Select a range that falls within your existing DMZ subnet. For example, if your DMZ uses the 192.168.50.0/24 subnet, and you want to support up to 30 concurrent NetExtender sessions, you could use 192.168.50.220 to 192.168.50.250, providing they are not already in use.
•
Select a range that falls within your existing LAN subnet. For example, if your LAN uses the 192.168.168.0/24 subnet, and you want to support up to 10 concurrent NetExtender sessions, you could use 192.168.168.240 to 192.168.168.250, providing they are not already in use.
To specify your global NetExtender address range using a Static IP:
1
Navigate to the NetExtender > Client Settings page.
2
Under NetExtender Client Address Range, select Use Static Pool from the drop down list.
3
Supply a beginning client IPv4 address in the Client Address Range Begin field.
4
Supply an ending client IPv4 address in the Client Address Range End field.
5
Under NetExtender Client IPv6 Address Range, optionally select Use Static Pool from the drop down list.
6
Supply a beginning client IPv6 address in the Client Address Range Begin field.
7
If using IPv6, supply an ending client IPv6 address in the Client Address Range End field.
8
Click Accept.
9
The Status message displays Update Successful. Restart for current clients to obtain new addresses.
To specify your global NetExtender address range using a DHCP:
1
Navigate to the NetExtender > Client Settings page.
2
Under NetExtender Client Address Range, select Use DHCP from the drop down list.
3
Under Select Interface, use the drop down list to select the interface to use for DHCP.
4
Supply the DHCP Server in the field provided.
5
Under NetExtender Client IPv6 Address Range, optionally select Use DHCP from the drop down list.
6
Under Select Interface, use the drop down list to select the interface to use for DHCPv6.
7
Supply the DHCPv6 Server in the field provided.
8
Click Accept.

The Status message displays Update Successful. Restart for current clients to obtain new addresses.
