COMMAND DESCRIPTION
[no] ip proxy-arp
activate
Enables proxy ARP on this interface.
The
no command disables proxy ARP on this interface.
[no] ip proxy-arp {ipv4
| ipv4_range |
ipv4_cidr}
Sets the proxy ARP target IP address, IP address range or IP address subnet on
this interface.
ipv4: IPv4 address <W.X.Y.Z>
ipv4_range: Range of IPv4 addresses <W.X.Y.Z>-<W.X.Y.Z>
ipv4_cidr: IPv4 subnet in CIDR format, i.e. 192.168.1.0/32 <W.X.Y.Z>/<1..32>
The Zyxel Device answers external ARP requests only if they match one of
these inputted target IP addresses. For example, if
ipv4 is 192.168.1.5, then
the Zyxel Device will answer ARP requests coming from the WAN only if it
contains 192.168.1.5 as the target IP address.
The
no command disables the proxy ARP target IP address, IP address range
or IP address subnet on this interface.
