Quickly proxy arp help you when you want a router answer to an ARP request if the destination address is in another interface of the linux router... Example: 192.168.1.1 ---- 192.168.1.2 Linux router 192.168.2.2 ----192.168.2.1 To get this example working you should: Without proxy-arp 1. In 192.168.1.1 host to set 192.168.1.2 as gateway 2. In 192.168.2.1 host to set 192.168.2.2 as gateway 3. pinging with success from any edge. With proxy-arp 1. In 192.168.1.1 host to set 192.168.1.2 as gateway 2. do not set gateway for 192.168.2.1 host but enable proxy_arp for right interface of the router. 3. pinging with success from any edge Proxy-arp in 2. case let the linux router answer when you ping from 192.168.2.1 host, saying that it has the 192.168.1.1 host so it can answer for it. After, when the source start sending ICMP packet, Linux router knows that it have to redirect it to the real host 192.168.1.1 In Wireless network proxy arp can help you if you have many Linux boxes that acts as IP Forwarders and you wouldn't set to all hosts a number of static route. You also can experiment Linux bridging in Wireless network: 1. install a recent stable kernel 2. download good bridge utils at http link or ftp link Bridging should be more simple to manage. http://www.tldp.org/HOWTO/Wireless-HOWTO-10.html - --- end I wish you have a good day, and a nice work donne with GNU-Linux.
