Troubleshooting

VPN Passthru: most home wireless routers have or have added in their latest firmware a specific option to "allow VPN passthru". Unfortunately, most of the time this option is disabled. You will need to connect to your router and enable this for VPN to work. If there is more than one option, enable the option for PPTP VPN Passthru. Consult your router's manual or the manufacturer's website for detailed instructions.

Protocol 43/GRE Issues: Some home routers do not support Protocol 43/GRE PPTP passthrough which our VPN service requires. If you bypass your router and find that you are able to connect, check with the manufacturer of your router for a firmware update.
