Accessing Your ChronoAgent Mac Across the Internet


This guide was written to assist in connecting to your ChronoAgent Mac across the Internet from your iOS device running InterConneX or Mac running ChronoSync. If you have questions regarding ChronoSync, ChronoAgent, InterConneX, or anything else mentioned in this guide, please contact


To access your ChronoAgent Mac across the Internet, you need to know its IP address. This is a unique number, similar to a phone number. Unfortunately, many internet service providers utilize dynamic IP address assignment. This means that from one internet session to the next, the IP address of your ChronoAgent Mac may change. The solution is to have a consistent mechanism to allow you to find your ChronoAgent Mac. We recommend using one of the free Dynamic IP Address Services available.

The Dynamic IP Address Service allows you to create a unique name by which you can locate your ChronoAgent Mac across the internet. This works by using ChronoAgent’s built-in Dynamic DNS client that periodically checks for changes in the IP address and updates the record that associates the unique name you create with your ChronoAgent Mac’s IP address. isn’t the only dynamic IP address service provider, but the service they do provide is free, unlike many other alternatives, so we’re using them in this guide as an example. If you decide not to use, the steps provided here for configuring the NoIP daemon will be similar when using other Dynamic DNS services/software.


  1. From the ChronoAgent Mac, go to and create a free account by clicking "Sign-up".
  2. During the Sign Up process, go ahead and create a hostname as directed.
  3. When signing up for a NoIP account, there are two different types of accounts - free and paid. With free, you have to keep the account alive whereas with paid, you don't have to worry so much about expiration. This guide uses the free account, but you can update to paid if you get everything working to your satisfaction.
  4. Once finished, you'll be sent an email containing a link to authenticate your account.


Make sure ChronoAgent is installed, configured and running on the Mac you want to access across the internet. The following screencast will walk you through this:

There are a few additional options to configure:

  1. Security. Open ChronoAgent to the Advanced Panel and make sure the Settings popup is set to 'Security'. Encrypt communications by enabling "Require All Connections to be Secure".

  1. Router Configuration. Now change the 'Settings' popup to 'WAN Access'. In the 'Router' section, enable the "Allow agent to automatically configure the router to accept incoming connections", but leave the WAN port field blank. Click 'Test Router' and the port will be automatically chosen.

  1. Dynamic DNS Configuration. In the 'Service Discovery' section, enable the 'Dynamic DNS service' checbox and choose 'No-IP' from the popup. If you’re using a different service, choose it from the popup list. Fill out your user credentials and Dynamic DNS hostname, then click 'Test DDNS'. If all goes well, you should see a 'The DDNS settings are valid' message as shown below.
Set up Dynamic DNS
  1. Status Panel. Switch to the Status Panel of ChronoAgent, then start the ChronoAgent service by toggling the OFF/ON switch. You should see a 'WAN Details' section. The port and URL hostname are what you’ll be using to connect to the ChronoAgent Mac from ChronoSync or InterConneX.

These instructions are based on the following video with a few modified steps:

  1. Connecting to the ChronoAgent Mac. When you go to choose an available ChronoAgent, choose Internet Address.

  1. Proceed with the rest of the steps as shown in the video.


These instructions are based on the following video with one modified step:

  1. Connect to ChronoAgent Mac. Tap Test Reachability and you should see the following message.
Enter NoIP hostname in ChronoSync
  1. Enable Advanced Options. In the Advanced Panel of the connection profile, enable "Automatic Reconnect on Drops" to have ChronoSync attempt to reconnect automatically upon connection loss and "Force All Data to Be Encrypted" to encrypt all data transmitted across the Internet.
