Cisco VPN 3000 Concentrator

[Groomes, Jay]

All,   I am having a problem getting the VPN 3000 Concentrator to authenticate users to our network.  The user are using a dial-up connection in order to VPN in, but they are receiving the error, “Remote Peer has lost connection”  I have searched through the firewall logs and saw that is does accept IKE traffic, but it denies bnews traffic.  What is the bnews service?    Also, I check the VPN logs, and it states the error, “Duplicate first packet detected!”  Is there a fix for this error? And what does this error mean?  Could it the problems reside on the ISP side?   All help is greatly appreciated!   Jay
