Just for curiosity's sake, check the UPnP settings on both machines. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ray Spaulding Sent: Monday, October 11, 2004 2:04 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: [hlds] NAT transparency with listenservers
I have also notice this. And here's my proof of it: I have a NAT network run on XP Pro. All other machines in the LAN have non-routable IPs. As most of you know, you cannot create rules of forwarding in client versions of WIN products without modification or programs. This setup is also XP firewalled by all the machines in the house under the SP2 update recently released from MS. I started a server on machine 192.168.0.131:27055 for testing of CS Source. I ran it a couple minutes and then fired a CZ server on the same machine to test for cpu usage. As I was firing up this second server I was surprised to see someone join the first CS:Source server. As I gaped at this, supposedly, impossibility I witnessed the same thing happen to the CZ server running on that same machine at port 27050. In my amazement I went to two other machines in the LAN and joined that server. And then started to play with the guy connected to the server on 192.168.0.131:27055! Additionally I went to the main hub of the LAN located at 192.168.0.1/66.31.77.xx and turned on HLSW pointing to the LAN server. He was fully connected in the game and having a blast. I turned HLSW to the CZ server I had running with bots for testing and found the same thing with 3 people in it. I have lacked posting here as I thought it a fluke and forgot about it as I shut the servers down. The one thing I failed to do was look on the Master List to see if my IP was there running at my public IP:27055 or whether or not it was modified by the NAT function in XP Pro to a random port for outgoing connections. I look forward to doing so tomorrow though just to test that theory. Ultimately, without a doubt, STEAM is bypassing the normal rules of routing and allowing connections to LAN systems from the internet. Now if THIS isn't a MAJOR security issue with this garbage then nothing else is. I look forward to responses to this and other people's experience on this one.

I'm behind a fairly restrictive NAT/router with nothing forwarded to my comp. Much to my surprise, some guy joined my game. Is there some kind of NAT transparency with HL2, much like that of UT2K4? --AgentHH _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
