Objective: To promote awareness of Microsoft Virtual Private Networking (VPN) problems experienced with USR Total Control Manager Terminal Servers. Test Equipment for Experiment #1: VPN Server: Microsoft NT 4.0 (SP5) Server 100base-T Ethernet VPN Client: Windows 98 Standard Modem 33.6 kbps Environment: a) An NT user account was created with logon locally services rights. b) MS-VPN and Remote Access (RAS) was configured for remote connectivity and VPN with 1 available network. c) Private class-c IPs were assigned to the VPN network for dynamically assigned addressing of remote clients. d) Network Domain was configured and named XYZ e) Win 98 machine was configured for Dial-up Networking including Dial-up adapter, TCP/IP and Microsoft Virtual Private Networking Dial-up adapter, and VPN Networking. f) Win 98 domain (workgroup) was set to XYZ. Dialup networking Test Results: (Livingston Port Master 2e) Using the standard Dial-up networking in Windows 98, I established an Internet connection to GTI using the analog Livingston Port Master 2e. I verified my connectivity by the use of such utilities as ping, traceroute and standard http, FTP and Telnet protocols. At that point I launched the VPN Dialup networking connection to the VPN server. The VPN server verified and authenticated my account and logged me in. I then ran a netstat utility to display my current Internet IP as well as the newly assigned private class-c IP provided by the VPN server. I could then go into Network Neighborhood and access every machine belonging to the XYZ domain, based on my account privileges previously configured at the VPN server user account manager. Test Results: (USR Total Control) Using the identical environments as above, I changed the dial-up node number to connect to the USR Total Control Terminal Server. The VPN authenticated my user account and logged me in, but there was absolutely NO connectively to the XYZ domain and the Internet connection completely stalled. Hypothesis: I believe the USR units are prohibiting the use of VPN somehow. Clients should be able to pass VPN packets regardless of what dialup they use. The Livingston 2e does not have a problem with VPN at all, so it looks like the USR is mis-configured somehow. Any insight would be appriciated. - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
