arplookup failed: host is not on local network

you get rid of this message by adding the network to your interface by this command.

route add -net ipaddress/mask -iface re0

for FreeBSD rc.conf add lines like

static_routes="netdirekt"
route_netdirekt="-net 217.20.117.0/24 -iface re0"

dont ask me how dirty this is, i am not responsable for our isps routing but for the logfiles

if you want to totaly disable arp notices

sysctl net.link.ether.inet.log_arp_wrong_iface=0
