Hello Mike,
Thank you for your message.
Remote Utilities uses ports 5655 and 443 for our Internet-ID connection, so it might work for you to simply use Internet-ID connection - our software will automatically try using port 5655 and then 443 to establish a connection.
In addition, you can always use
Direct connection which allows you to use any custom port value.
For more information on ports used by Remote Utilities, please see
this page.
Let us know if you have more questions.
