Hello all, I am writing a program for file transfer over internet with TServerSocket and TClientSocket. It work now but I have problems when the client is in lan with a proxy/firewall (in the office) and use it to block some ports. I have tried it and it seems that only the port 25 can be used for a connection with my server application (error code 10051 on others ports). I would like to know : - port 25 can be used by my application like another port or it is checked by proxy becouse it is for email ? - how can I modify my program to support proxy ? Thank you very much for help Alfred
