Stephen,
Thanks for your answer,
I ask this question because before installing my firewall on my map some of
my natted equipments where on my map without using CNAT.
But now that I put my Firewall in my seedfile the nated equipment have
disapeared and now they IP adresses appeared like interfaces.
So i thought there was a solution without using CNAT.
Cordialement.

Maxime,
Yes there is a solution to the problem. The problem is that the NAT
simply translates the header on the ICMP and SNMP packets coming back to
you. But SNMP packets that NetView is using also has addresses in the
payload of those packets. When NetView reads the MIB, it is getting IP
information in that MIB.
The solution is to install a CNAT (Comprehensive Network Address
Translator) between your NetView and NATed network. This is a Tivoli
product, you should be able to read about it on the web pages. It will
work WITH your firewall NAT. (It would also do the NAT for you if you
did not already have one).
There is a component of that product that installs on the NetView server so
that the server knows that these addresses are being translated.
Kind regards,
