William,

NetView can manage a NATed environment using CNAT.    Comprehensive Network
Address Translator.   CNAT 1.2 runs only on AIX.  When CNAT 2.1 is released
it will run on additonal platforms.    you can look at the product
documenation on www.tivoli.com .   For a decent explanation you can read
about the first version in a NetView 6.0 and Friends Redbook   on
www.redbooks.ibm.com

CNAT will allow NetView to manage a NAT network.   CNAT 1.2 can NAT the
payload/header or just the payload if the router is already doing the
header.

Kind regards,
