Please recheck with > the current HOWTO (http://ds9a.nl/lartc) if you are doing the right thing. Eh, he does nothing with proxy-arp. So I am really puzzled here. Especially the MASQ entries? Why? What? Glynn, would you care to explain your setup, more like what are you trying to do? Because: yes: you can have a proxy-arp "bridge" (remember, it will not learn anything) using a tunnel, connecting the same subnets. Both ends of the tunnel must exactly know where each system resides with respect to the tunnel. And no, this has nothing to do with netfilter, masquerading, etc. . You still are in the pure routing domain. -- <ard@telegraafnet.nl> Telegraaf Elektronische Media http://wwwijzer.nl http://leerquoten.monster.org/ http://www.faqs.org/rfcs/rfc1855.html Let your government know you value your freedom.
