In the DoProxy field, click enable to enable Proxy ARP function (see "Using Proxy ARP" for an explanation of the option).
The default is disabled.
In the DoResp field, click disable or enable to select whether or not to respond to an ARP, and then click Apply.
The default is enabled.
Note:
Use the ARP window when setting the ARP response behavior on a brouter port. To configure the ARP response for a routing VLAN, use VLAN > VLANs > Basic > IP > ARP. The ARP window is not applicable unless the port or VLAN is routed; that is it is assigned an IP address.
