How many DHCP leases and NAT clients? ISC's DHCPd typically runs a few tens of MB unless you have many tens of thousands of leases. State table for natd doesn't require much memory either, but it scales more with the number of network flows rather than just # of clients. One client pounding away with BitTorrent will use more NAT session states than a dozen clients under normal desktop use. Regards, -- -Chuck
