Click [Submit] to save the desired Single Port VLAN setting.
Proxy ARP Enable
Proxy ARP (Address Resolution Protocol) is a technique by which an NP Interface in Router Mode
on a given network answers the ARP queries for a network address that is not on this network, but
is reachable via the NP Interface.
With Proxy ARP enabled, the NP Interface (in Router Mode) 'snoops' all ARP_REQs; it will send an
ARP_REPLY (one if the ARP_REQ host address is an NP host address that is reachable via one of
the routes in the Route Table).
Using the drop-down menu, set Proxy ARP Enable as Enabled or Disabled.
Click [Submit] to save the desired Proxy ARP Enable setting.
