VPN tracker reset all references to our company domains to IPs that are relevant only when you are connected. It didn't release them on disconnect. Uninstalling didn't work nor did the company's uninstall application. A diligent search for preferences, etc. doesn't reveal where the problem lies. Requests for tech support from the company have not been answered and the company rarely is available to answer phone calls. They also don't return phone messages. Use this product with caution. If it works for you that's great, but if it doesn't you may have some real difficulty.
