Firewalls prevent unauthorized programs from accessing the internet and must be configured to allow TC2000 to connect to our servers. Disabling a firewall may correct some issues, but they can still interfere with programs if you have not specified that they should always be allowed to access the internet.

Please note: Worden Tech Support is not trained on how to configure your firewall, and we are only authorized to make changes to programs created by Worden Brothers, Inc.

If your firewall allows you to set Program Exceptions, please add sllauncher.exe

You may need to configure access to port numbers and/or server addresses. For TC2000 please make sure that ports 80, 443, 943 and 4500 through 4525 are open. The server addresses are www.tc2000.com, data.freestockcharts.com, dataprox.freestockcharts.com and images.freestockcharts.com

Note: Whenever possible, it is preferable to configure a firewall by server address instead of IP address. If the firewall or network filters only allows specific IP exceptions, use the instructions in the ‘How to Determine IPs’ section below. If an IP range exception can be entered, please enter 64.239.246.132 through 64.239.246.190

Note: From time to time, IP addresses will change without notice. You will need to reconfigure the firewall anytime a server address moves to a new IP.
