HI, I''ve got a proxy arp setup with iptables and tc. on eth0 i have a route to 172.16.2.0/24 network on eth1 is the LAN of 172.16.1.0/24 network I have enabled proxy arp on both interfaces. Now accordingly, the interface will respond to all ARP requests for which it has a route to. Noy my setup is such, that a user on the LAN, would like to have an ip from the 172.16.2.0/24 network. But unfortunately, when he tries to allocate an ip like 172.16.2.1 he gets an ip conflict. I also know why he is getting it! But is there any way out of this?? Something like, tell the linux server to respond for ARP requests for the 172.16.2.0/24 network but at the same time if a machine is trying to use an ip for itself, then it should not respond.

But you should add such route not only for escaping the ip conflict. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
