Firewalls are a popular and effective security option designed to block unauthorized outgoing and incoming communications with your computer.
Some firewalls require additional steps to authorize trusted applications like GoToMyPC. If you have a firewall and are experiencing connection difficulties, follow the instructions below to reconfigure firewall.
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.
Configuring your firewall for GoToMyPC generally requires two steps:
Step 1: Grant permission in your firewall program
When you first install GoToMyPC on your host computer, GoToMyPC attempts a secure connection with the Citrix communication servers. This connection process could trigger firewall alerts that will prompt you for action.
If your firewall does not automatically ask to allow GoToMyPC to access the Internet, you may have to enable it manually.
Step 2: Navigate and accept the GoToMyPC components
If you are using an older or expired security software, we recommend that you update it with the most recent version from its manufacturer. Even if a security program expires, its firewall component may still be active and could still cause GoToMyPC connection failures. If your security or firewall program has expired, we recommend either renewing the license so that you may configure its firewall or uninstall it and utilize a different security or firewall solution.
GoToMyPC periodically releases updates for both host and client software. You may need to update your security software to the appropriate version provided by your manufacturer in order for it to recognize newer versions of the GoToMyPC software.
