Frequently Asked Questions
Q.
My Internet Service Provider will not provide me with a Static external/public IP address. Are there other options?
A.
If you are unable to get a static external/public IP address from your ISP, you have two options:

Use the dynamic external/public IP address, if/when the IP address changes, repeat step 3 above to look up the
new external/public IP address.

Use a 3
rd
party dynamic DNS service provider.
There are a number of providers who provide a Dynamic DNS service. These are generally implemented in the
user's router or computer, which notices changes to its IP address and automatically sends an update message to
the DDNS service provider.
List of Dynamic DNS Service Providers:

dyn.com

no-ip.com

dnsdynamic.org

Troubleshooting Remote Connection Problems
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.
