I use VPN Software (Nortel Networks Contivity VPN Client v 4.15) to connect
to my network at work from my home computer. I recently upgraded to DSL from
dial-up, but have been unable to connect through my VPN to work from the DSL
connection. It gets to the point where it attempts to retrieve a standard
banner, then drops out. The messsage returned is "The secure Contivity VPN
connection has been lost. Click Connect to re-establish the connection". I
also get a "warning" on the System Event Viewer: "The server could not bind
to the transport \Device\NetBT_Tcpip_[BAB0F5B2-6F58-426A-91EA-93F34C847982]."
The Event ID is 2504. I have no problem connecting from dial-up if I switch
over, and otherwise have no problem connecting to the internet. I have
configured the firewall on my own machine to allow transmission over port
500, as required, but even turning off the firewall has no effect. I have
talked to the Support people at work, and they suggested it might be a router
configuration issue, but the DSL support people have been no help at all. I
have attempted to reconfigure the modem/router myself (the port forwarding
setting), but this has no effect either. The modem's firewall is turned off.
I am using a Dell Inspiron 5000e with the Windows XP (sp2) operating system,
an Actiontec GT701-WG DSL Modem and a Linksys PCM200 Network card. It is not
absolutely necessary to be able to connect through my DSL, but it is
extremely inconvenient to have to switch back to dial-up every time I want to
reach the net at work, and I really believe it is merely a configuration
issue. Csn anyone please help?

Thanks, Gary
