Connection through LAN

Hello,

i want to test the smartftp on a computer that is connected to a LAN, i am not an expert, the best example i can give is that the Win Explorer connection is setup through LAN using a Proxy Server at the adress 192.168.0.1 Port: 80, this IP.A is of the local server, and if i want to ping any other IP.A it is impossible, so, how should i need to configure the smartftp to work under this condition and that it finds the adresses like Win Explorer does?

One more thing, can you give me a FTP adress to test the application?

Best Regards!
