Overview

For browsers on the client machines to automatically detect Kerio Control settings via DHCP and use the Kerio Control non-transparent proxy server, Kerio Control and the web browsers both should be configured accordingly so that the client machines can access the internet.

Solution

The non-transparent proxy server should be setup in your Kerio Control environment before proceeding with the below steps:

1. In the Kerio Control administration, go to Configuration > Proxy Server.
2. Select the Allow browsers to use configuration script automatically via DHCP server in Kerio Control option.
   Note: The DHCP server configuration/deployment in your environment is independent of Kerio Control.
3. Click on the Apply button.

The next set of steps should be performed on all the client machines that will connect via Kerio Control:

1. Browsers on client machines must choose the option to automatically detect settings and/or automatic proxy configuration script/URL in the proxy server settings. Below are examples of these settings for the Google Chrome and Mozilla Firefox browsers:

2. The following address should be added to the appropriate settings: http://vvv.xxx.yyy.zzz:3128/pac/proxy.pac where vvv.xxx.yyy.zzz is the IP address of the Kerio Control host and the number 3128 represents the port of the Kerio Control proxy server.

Note: The automatic configuration of browsers may take several hours since the browsers must ask for a new configuration.

Testing

Users should be successfully able to connect using Kerio Control and browse the internet as per their settings.

In case there is a failure to connect, create a local IP address group of the clients that connect to Kerio Control and then create a traffic rule that allows them in.

If the connection failures persist, then, open a support request with us with the Support information file that can be saved by logging into Kerio Control administration and going to Status > System Health > Support information.
