Enter a name for the DHCP scope.
Type
Select any of the following options:
l Local— On selecting Local, the DHCP server for local branch network is used for
keeping the scope of the subnet local to the IAP. In the NAT mode, the traffic is
forwarded through the IPSec tunnel or the uplink.
l Local, L3—On selecting Local, L3, the Virtual Controller acts as a DHCP server and
gateway. In this mode, the IAP routes the packets sent by clients and also adds a
route on the controller, after the VPN tunnel is set up during the registration of the
subnet.
VLAN Specify a VLANID. To use this subnet, ensure that the VLANID specified here is
assigned to an SSID profile. For more information on SSID profile configuration, see
Configuring VLAN Settings for a WLAN SSID Profile on page 97 and Configuring
VLAN for a Wired Profile on page 114

Netmask If Local or Local,L3 is selected, specify the subnet mask. The subnet mask and the
network determine the size of subnet.
Excluded address If Local,L3 is selected, specify the IP address to exclude. The value entered in the field
determines the exclusion range of the subnet. Based on the size of the subnet, the
lesser range of IP’s before or after the specified IP address will be excluded
DNS Server If required, specify the IP address of a DNS server for the Local and Local,L3 scopes.
Domain Name If required, specify the domain name for the Local and Local,L3 scopes.
