Thanks for your answer.
Sorry for waiter, is a server ... and the footbridge is a bridge betwen 2 diferents networks.
Catia V4 is a software developped by Dassault system.
It's 2 servers windows 2003 in NFS.
The Cde office has started well today.
My database is put together well.
On the contrary, the environment erase the recorded static roads.
It's a directory with files for catia V4 and Cde office, I've recup it on the server Aix and put it in a directory of the server 192.168.0.200.
I do not know how to change it or to find resolution.
It would be simpler to be able to achieve the server Aix directly via the server windows 2003 with the 2 cards networks.
