Figure 56 The Proxy ARP Screen
Proxy ARP is a variation of Address Resolution Protocol (ARP), in
which an intermediate device (in this case, the Router) sends an ARP
response on behalf of an end node to the requesting host. Proxy ARP
can help decrease bandwidth consumption on slow-speed WAN links
and allows a site to use a single IP address for two physical networks.
To use proxy ARP, you must have a range of static IP addresses
assigned by your ISP.
Proxy ARP only works when the Router is assigned a static IP
address.
To configure Proxy ARP:
1 On the menu, click Advanced.
2 Click the Proxy ARP tab.
3 Select the Enable Proxy ARP check box.
