11. Set or override the following network information from within the IP Addresses field:
12. Refer to the DHCP Relay field to set or override the DHCP relay server configuration used with
the virtual interface.
13. Define or override the Network Address Translation (NAT) direction.
Select either the Inside, Outside or None radio buttons.
• Inside - The inside network is transmitting data over the network its intended destination.
On the way out, the source IP address is changed in the header and replaced by the
(public) IP address.
• Outside - Packets passing through the NAT on the way back to the managed LAN are
searched against to the records kept by the NAT engine. There the destination IP address
is changed back to the specific internal private class IP address in order to reach the LAN
over the switch managed network.
• None - No NAT activity takes place. This is the default setting.
NOTE
Refer to Setting the Profile’s NAT Configuration for instructions on creating a profile’s NAT
configuration.
14. Select the OK button to save the changes and overrides to the basic configuration. Select
Reset to revert to the last saved configuration.
15. Select the Security tab.
Enable Zero
Configuration Zero configuration can be enabled and set as the Primary or Secondary means of providing IP
addresses for the virtual interface. Zero configuration (or zero config) is a wireless connection utility
included with Microsoft Windows XP and later as a service dynamically selecting a network to connect
based on a user's preferences and various default settings. Zero config can be used instead of a
wireless network utility from the manufacturer of a computer's wireless networking device.
Primary IP Address Define the IP address for the VLAN associated virtual interface.
Use DHCP to Obtain IP Select this option to enable DHCP to provide an IP address for the virtual interface. Selecting this option
disables the Primary IP Address field.
Use DHCP to obtain
Gateway/DNS Servers Select this option to allow DHCP to obtain a default gateway address, and DNS resource for one virtual
interface. This setting is disabled by default and only available when the Use DHCP to Obtain IP option
is selected.
Secondary Addresses Use the secondary addresses parameter to define additional IP addresses to associate with VLAN IDs.
The address provided in this field is used if the primary IP address is unreachable.
Respond to DHCP Relay
Packets Select the Respond to DHCP Relay Packets option to allow the onboard DHCP server to respond to
relayed DHCP packets on this interface.
DHCP Relay Provide IP addresses for DHCP server relay resources.
The interface VLAN and gateway should have their IP addresses set. The interface VLAN and gateway
interface should not have DHCP client or DHCP Server enabled. DHCP packets cannot be relayed to an
onboard DHCP Server. The interface VLAN and gateway interface cannot be the same.
When changing from a default DHCP address to a fixed IP address, set a static route first. This is critical
when the controller or service platform is being accessed from a subnet not directly connected and the
default route was set from DHCP.
