Note for Netgear Routers

If your connection will not let you through and you have a Netgear router, you might also need to disable the SPI firewall.

  1. Boot up your web browser and enter the IP for your router (probably 192.168.1.1).
  2. Enter the admin user/pass for the router.
  3. Under "Advanced", select "WAN Setup".
  4. Uncheck "Disable SPI Firewall".
  5. Click "Apply" and wait for the router to do its thing.

Connecting to the VPN

Go back to the Network and Sharing Center.

  1. Select "Connect to a network".
  2. The icon for Networking should pop up a selection screen; select your VPN connection, then click the "Connect" button.

General Troubleshooting

Some things to try

  1. Other gateway devices have this SPI Firewall (Stateful Packet Inspection), disable it under Advanced or Security settings.
  2. Also under Security settings, you may have a setting for "PPTP pass-through", make sure this is enabled.
  3. Upgrade your gateway (Linksys, Netgear) to the latest firmware.
  4. Try from a DOS prompt: TELNET nvfirewall2.netsville.com 1723. If you get a new window to come up (black screen), that means the port is open (that's a good thing!). If not, and it just sits there with Connecting to nvfirewall2.netsville.com..., that means you are getting blocked by some kind of firewall and you need to fix that before trying anything else. One of our customers had this problem and solved it by upgrading the firmware of their Linksys WRT54G.
