New topic in General: Creating a Firewall - Stealth port
jclevien - Wed Apr 16, 2008 6:41 pm <http://forums.realsoftware.com/viewtopic.php?t=21873> Hello, I am planning to create a firewall - router program to administer network connections. One thing I cannot figure out, is: how can I convert TCP and UDP ports to be "stealth"? I mean, when you probe you firewall with Shields UP, if your firewall is OK, it shows all ports "stealthed" (not only blocked or disconnected). Yes, I can "refuse" a connection by simply disconnecting it when it attempts to connect. But I would like something more secure, is there a way to hide ports with REALbasic? I am thinking about the ServerSocket class - you instantiate a ServerSocket per port you want to listen. But what happens if you don't return a socket in the AddSocket event? Will it work like the Stealth mode if you return Nil or the like? Thank you for your answers.
