proxy arp การใช้

Proxy ARP can create DoS attacks on networks if misconfigured.
If it does, MACFF uses a form of Proxy ARP to reply to any ARP requests, giving the router's MAC address.
In such a case direct communication between the IP hosts on the protected ports is only possible through the uplink connection by using MAC-Forced Forwarding or a similar Proxy ARP based solution.
:The access router uses Proxy ARP to make the dial-up node present in the subnet without being wired into the Ethernet : the access server'publishes'its own MAC address for 192.168.0 . 254.
For example, a misconfigured router with proxy ARP has the ability to receive packets destined for other hosts ( as it gives its own MAC address in response to ARP requests for other hosts / routers ), but may not have the ability to correctly forward these packets on to their final destination, thus blackholing the traffic.
