Proxy ARP (Address Resolution Protocol)
ARP requests
The
➤➤
Proxy ARP
function enables
X4000
to answer
➤➤
ARP
requests
from the LAN. That is, if a host in the LAN wants to set up a connection to
another host in the LAN or to a WAN partner but doesn’t know its hardware
address, it sends a so-called ARP request into the network as a
➤➤
broadcast
. This is actually a question to all those in the network: "What
is the hardware address of host x?" If Proxy ARP is activated in
X4000
and the
desired host can be reached over a defined WAN connection,
X4000
answers
the ARP request with its own hardware address. This is sufficient for
establishing the connection: The
➤➤
data packets
are sent to
X4000
, which
then forwards them to the desired host.
