Firewalls are a popular and effective security option that are designed to block unauthorized outgoing and incoming communications with your computer. Some firewalls require additional steps to authorize trusted applications like GoToMyPC. If you are have a firewall and are experiencing connection difficulties then the configuration instructions should be of some help.
Note: The GoToMyPC components need to be admitted through three ports: 80, 443 and 8200. One-way TCP connectivity is needed (TCP outbound). Please visit our IP Range Fact Sheet for more information.
Configure a Firewall on the Host Computer
Configuring your firewall for GoToMyPC generally requires two steps:
Step 1: Open permission settings in your firewall program
When you first install GoToMyPC on your host computer a secure connection with the Citrix Online's communication servers is attempted. This connection process could trigger firewall alerts that will prompt you for action.
From the firewall alert select the check box to Remember the answer each time I use this program.
Click Yes to enable GoToMyPC to access the Internet.
If your firewall does not automatically ask to allow GoToMyPC to access the Internet, you may have to enable it manually.
