KB0074: Troubleshooting Port Forwarding / Remote Connection with Universal Time Clock/ TotalPass P400
If you are unable to connect to your time clock using the external/public IP address you will need to troubleshoot your connection and configuration.
- Restart your router.
- If you are using both a router and a cable modem router/DSL modem router for port forwarding, ensure that port forwarding has been configured on both the router and cable modem router/DSL modem router.The cable modem router/DSL modem router must port forward to the local static IP address assigned to the secondary router.Alternatively you may contact your ISP to disable the router function on your cable modem router/DSL modem router.
- Ensure that a static internal IP address has been assigned to the clock along with the proper subnet mask, DNS address, and gateway address. The time clock may need to be rebooted after assigning these values.
- Make sure that the correct time clock IP address and/or port number has been input in the port forwarding settings in your router.
- Make sure that the correct external/public IP address has been input in at the web browser.
- Make sure that there is not another device on the network that is using a duplicate IP address as the time clock.
- Check the filter settings on the router to be sure that it is not interfering with the connection.
- Use an open port checker, like www.yougetsignal.com to check your external IP address and detect open ports on your connection. For additional troubleshooting steps refer to www.portforward.com. Select your router by model name and number for specific port forwarding instructions.
