Windows SBS 2008 Standard VPN issues

I'm having issues getting VPN to work on a brand new Windows 2008 SBS Standard server.  I've run through the vpn wizard in the SBS Console.  Verified Port 1723 is passing through to the servers IP address and have both IPsec and PPTP passthrough enabled on the router.  I'm getting an error 800 but can't figure out why it is not authenticating.

in the above article if you suspect your hardware firewall might be causing an issue, see this section "Configuring the External Hardware Firewall for VPN Virtual Private Network access"

The error 800 indicates that the PPTP/L2TP packets from the VPN client
cannot reach the VPN server. Please make sure that port 1732 can be
accessed from the clients and you may run "netstat -ano |find "1723"" to
indentify the port is listened for PPTP VPN.

It turns out you were correct about the packets not getting to the VPN Server.  1723 was open, but it turns out the issue was a faulty router.  blah!
