From my experience, a fast P4 linux box with 2 good NICs can NAT 45Mbps =
easily.  I am NAT/PATing >4,000 desktops with extensive access control =
lists and no speed issues.  This isn't over a 45Mb T3--this is over 100 =
Mb Ethernet.

doing NAT will not be able to handle the load."   I am not really =
