Got a strange one that I've never seen before.  As far as I know, no changes have been made to the configuration prior to this occurence that began yesterday.

I have field users trying to dial in to our SBS 2008 server via Microsoft VPN.  Our Sonicwall Pro 2040 is seeing the attempts and not passing them through to our server.  The Sonicwall is instead trying to handshake with the users VPN dial in attempts.  

Not sure what information anyone would need to help with this problem.  Just let me know and I'll be quick to provide it.

    you need to configure the firewall to forward the vpn requests to the SBS server. Which type of service are you using for VPN (L2TP, PPTP) ?

    Yeah, I figured as much.  Considering we've made no changes though I'm curious as to why it just started happening (been stable for the past year).  Anyways...I have the client VPN's set up as Automatic.  If I were to manually change them, I'd make them PPTP.

    It ended up that I had 1723 forwarded to mutliple systems.  Rookie mistake.  Thanks for the help.
