Hi,

I have an FreeBSD amd64 9-STABLE system running as a router for various 
bits and pieces - this has a 'lot' of hosts on it's LAN (literally 
thousands) - most are NAT end points etc.

Looking at the output from 'arp -a -n' it regularly lists 2,000-3,000 
entries. Is there anything I need to tune for this kind of quantity (or 
more), or is it all 'auto-adjusting' on 9.0-S onwards?

Thanks,

-Karl
