Somewhere in the net I found this:

echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh3

Now do I just need to do that once?  Do I need to reboot/restart interfaces after? 

On reboot do I need to remind my system of this?  Where would be the optimal place (debian system)?
