I personally started solving the problem that Proxy ARP is meant to solve with a different solution. I fell in love with Linux bridges (brctl, etc) for things like this (I'm guessing) 15+ years ago. I can create a Bridging Router (a.k.a. BROUTER) that combines layer 2 and layer 3 functionality. This allowed me to bridge non-IP protocols, like NetBIOS / IPX, while routing IP. I could further extend things to include selectively bridging IP via adding EBTables to the mix. I did a LOT of crazy things with Linux bridges. }:-) In hind sight, Proxy ARP might have been the simpler solution. Though I think Proxy ARP would have required that I configure IPs to be Proxy ARPed on all intermediate hosts. Where as bridging has it's own inherent L2 learning. (At least when I was working with non-IP protocols.) I don't know how well Proxy ARP plays with things like OpenVPN or OpenSSH layer 2 tunnels. - I know that I can easily extend layer 2 across a LARGE majority of networks using Linux bridges. - I think that I can even bridge any type of network that uses 802.2 Link Level Control headers. I.e. Token Ring (802.5) and Ethernet (802.3) and Wireless (802.11) and various tunnels. -- Grant. . . . unix || die
