I see more programs coming out lately that are using http-tunneling to "punch-through" firewalls. Take Skype for an example, you don't even have to tell it any firewall information; it does its own probes and figures out how it can get through. Getting a bit more difficult to filter the tunnelers, they look like normal web traffic... What's your take on them? -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Wednesday, April 13, 2005 22:19 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Terminal Service Port Change? http://www.ISAserver.org Hey Jim, You being in the belly of the beast, as it were, you might have some insight into why developers of network enabled application don't seem to realize that there are these fancy things called "firewalls" that control access to and from the Internet, you know, for security reasons and stuff. Did they miss that meeting, or not even get the memo? Tom www.isaserver.org/shinder Tom and Deb Shinder's Configuring ISA Server 2004 http://tinyurl.com/3xqb7 MVP -- ISA Firewalls
