I use ProxyARP because it is the only thing that made sense to me. In "iptables speak", the external interface receives all packets destined for my /29 network but it puts into INPUT only those with the IP I assign to the NIC. The rest go to the FORWARD chain and thus on to 4 "internal" machines that have external IPs. Two of those "internal" machines have 2 external IPs. I do that like this: ifconfig eth1 IPAddr1 broadcast BcastIP1 netmask 255.255.255.248 ifconfig eth1:0 IPAddr2 broadcast BcastIP2 netmask 255.255.255.248 ip route add GatewayIP2/32 dev eth1 src IPAddr2 On the machine doing ProxyARP: ip link set eth1 up ip addr flush dev eth1 ip addr add dev eth1 local 1.1.1.2/32 brd 1.1.1.255 ip route add GatewayIP/32 dev eth1 src 1.1.1.2 You can see my scripts at http://yesican.chsoft.biz/lartc and you can get more from ftp://andthatsjazz.org/pub/lartc -- gypsy _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
