Hi all, thanks for your answers and help, the firewall is in place and allows all necessary traffic. There might just still be something I forgot to mention : the linux box firewalling the internal network is also a web server (for the outside) and keeps sending its own Apache messages to whatever http transaction is asked. Any ideas where that comes from ? TIA ilan [EMAIL PROTECTED] [EMAIL PROTECTED] _________________________________________________________ Do You Yahoo!?
