Message Really sorry for the " Mr " didn't pay attention please know that I have = for you the utmost respect and appreciation. The relation between server and client is Internal there is no = communication with the external network : 172.26.30.20 is the server IP Adress 172.26.30.17 is the Client Ip Adress When the client is configured as a SecureNAT client it works, when its = configured as a Firewall client, it doesn't work. Only the host command it give the order to the oracle server to write on = database and the client freeze it doesn't pass to next step but if i = check the server i find that the file i load to write on the server is = actually writen but it stops there . ps: If i disable the ferwall client it also stop functionning i need to = uninstall it completly in able to work. Georges Khoueiry IT Consultant Hi Georges, First, its either Dr. Shinder or Tom. I prefer the latter. I haven't been "Mr." for almost 15 years :) From what I can tell, your have an internal network client that can't access some type of Oracle application on the external network. When the client is configured as a SecureNAT client it works, when its configured as a Firewall client, it doesn't work. Is that right? Thanks!
