Linux instead does automagic proxy arp when a route exists and it is forwarding. See arp (7) for details. Also the dontpub option which is available for delete and set operations cannot be used with 2.4 and newer kernels.

It also allows a complete dump of the ARP cache. ARP stands for Address Resolution Protocol. The primary function of this protocol is to resolve the IP address of a system to its mac address, and hence it works between level 2(Data link layer) and level 3(Network layer). Hi, Your layer-3 switch SVI acts as the proxy for the hosts or clients which are not in the same subnet, same as a router does. So when a arp requests comes for a client which is on the other subnet and as the Layer3 device doesnot maintain a CAM table, it will act as the proxy and provides its MAC for the ARP resolution. With Linux 2.4/2.5 (and possibly 2.2), this possibility has been withdrawn and has been replaced by a flag in the /proc directory, called 'proxy_arp'. The procedure for building a pseudo-bridge is then: G1, G2, and G3 are instances of Linux on z/VM® (connected, for example, through a guest LAN to a Linux router R), reached from GW (or the outside world) through R. R is the ARP proxy for G1, G2, and G3. That is, R agrees to take care of packets that are destined for G1, G2, and G3.

I need to perform a simple operation to publish the server to the Internet. For this: 1. I create a manual static nat 2. Add the address in the proxy arp via WEB-UI (85.21.100.105 - Public server IP) 3. I turn on the global settings option "Merge manual proxy ARP configuration" 4. install policy. B

Proxy ARP is a technique by which a proxy device on a given network answers the ARP queries for an IP address that is not on that network. The proxy is aware of the location of the traffic's destination, and offers its own MAC address as the (ostensibly final) destination.

The bridge host will proxy ARP requests from the inside network to the outside, and respond to ARPs from the outside network on behalf of inside hosts. Linux will only do this for hosts that are known via the routing table, so a /32 host route must be created pointing to the inside host (one for each inside host).

Also, the dontpub option that is available for delete and set operations cannot be used with 2.4 and newer kernels. -s hostname hw_addr , --set hostname parprouted is a daemon for transparent IP (Layer 3) proxy ARP bridging. Unlike standard bridging, proxy ARP bridging allows to bridge Ethernet networks behind wireless nodes. Normal L2 bridging does not work between wireless nodes because wireless does not know about MAC addresses used in the wired Ethernet networks. 4. Setting up Proxy ARP with subnetting. I set up Proxy ARP with subnetting on a Linux kernel version 2.0.30 machine, but I am told that the code works right back to some kernel version in the 1.2.x era. All hope is not lost however….this is where proxy ARP comes to the rescue! When proxy ARP is enabled on the router, this is what happens: The router sees the ARP request from H2 on the 10.1.1.0 /24 subnet and sees that this is an ARP request for something in the 10.2.2.0 /24 subnet.
