An Arp Publish Ethernet Frame - D-Link DFL-1660 User Manual

3.5.3. ARP Publish
These are shown in the illustration below of an Ethernet frame containing an ARP response:
The Publish option uses the real MAC address of the sending interface for the address (1) in the
Ethernet frame.
In rare cases, some network equipment will require that both MAC addresses in the response (1 and
2 above) are the same. In this case XPublish is used since it changes both MAC addresses in the
response to be the published MAC address. In other words, XPublish "lies" about the source address
of the ARP response.
If a published MAC address is the same as the MAC address of the physical interface, it will make
no difference if Publish or XPublish is selected, the result will be the same.
ARP and Neighbor Discovery
Neighbor Discovery with IPv6 is the equivalent of ARP with IPv4. For this reason, ARP and
neighbor discovery are combined in The graphical interface to NetDefendOS uses the same dialog
to add either one. Neighbor Discovery is discussed further in Section 3.2, "IPv6 Support".
Example 3.20. Defining an ARP/Neighbor Discovery Object
This example will create a static mapping between IPv4 address 192.168.10.15 and Ethernet address
4b:86:f6:c5:a2:14 on the lan interface:
