#### How do I know if OTG 1 is working on my Mac?

There are a number of ways to check if OTG 1 is working on your Mac:

• If OTG 1 is configured to show notifications in the menu bar, you can rollover the icon to see its status:

Connected shows when OTG 1 is filtering.

• Perform a command line nslookup on a domain that is known to be blocked by your policy. If the lookup returns the IP of WebTitan Cloud (which is its block page), then filtering is working.

• When filtering, your network card’s IPv4 properties will have the DNS server settings changed to 127.0.0.1.

#### Can users manually change their DNS settings and bypass OTG 1?

Once a user has administrative privileges to their machine, they can manually change their DNS settings and bypass any filtering system.

#### Where are the OTG 1 logs on Mac?

Logs and post-install config files are located at:

<user_home>/Library/Application Support/WebTitan Cloud OTG/logs

#### Where is the OTG 1 configuration file on Mac?

The OTG 1 configuration file config.ini is located at:

/Library/Application Support/WebTitan Cloud OTG/config.ini

#### How can I uninstall OTG 1 on a Mac?

1. Open a terminal window.

2. Run this uninstall script:

sudo /Applications/WebTitanCloud.app/Contents/Resources/uninstall.sh

#### How does OTG 1 work with a VPN?

Normally OTG 1 manages the DNS settings for all network adapters and assigns them a DNS IP of 127.0.0.1. However, OTG 1 is bypassed on VPN adapters. If OTG 1 detects a VPN adapter, it will not change its settings.

Therefore, if DNS requests are going through a VPN, they are unfiltered and the DNS server at the end of the VPN tunnel must be configured to apply filtering as required.

#### What reports are available on roaming users?

Go to Reporting > Reports where there are a number of report options available:

• Select 'Requests by Users' or 'Requests by Location' from Choose Report Type

• Drill down by User for further detail or create a filter to report further by User.
