Determine the correct subnet based on your network scenario
selection:
Scenario A
192.168.200.100 to 192.168.200.200 (default
range)
Scenario B
Select a range that falls within your existing
DMZ subnet. For example, if your DMZ uses
the 10.1.1.0/24 subnet, and you want to
support up to 30 concurrent NetExtender
sessions, you could use 10.1.1.220 to
10.1.1.249.
Scenario C
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
192.168.168.249.
NOTE: DHCP/DHCPv6 is supported and can manage the
IPv4 and IPv6 addresses in the LAN and the NetExtender
client address ranges.
To set your NetExtender address range:
1 Navigate to the NetExtender > Client Settings page.
2 Enter an address range in the Client Address Range
Begin and Client Address Range End fields.
3 Click Accept to add the Client Address Range.
Scenario A
192.168.200.100 to 192.168.200.200
(default range)
Scenario B
An unused range within your DMZ subnet.
Scenario C
An unused range within your LAN subnet.
If you do not have enough available addresses to support your
desired number of concurrent NetExtender users, you may use
a new subnet for NetExtender. This condition may occur if your
existing DMZ or LAN is configured in NAT mode with a small
subnet space, such as 255.255.255.224, or more commonly if
your DMZ or LAN is configured in Transparent mode and you
have a limited number of public addresses from your ISP. In
either case, you may assign a new, unallocated IP range to
NetExtender (such as 192.168.10.100 to 192.168.10.200) and
configure a route to this range on your gateway appliance.
