Agent Based Apps

To configure agent based applications, provide the following application details:


Setting Up Agent-Based Apps

To configure agent-based applications, provide the following information. For more details on Seqrite Universal Agent, refer to the Seqrite Univeral Agent and Deployment Sections.

1. Application Information

• IP Address or Domain Name: Enter the IP address or domain name of the application.
• Protocol: Select the appropriate protocol from the dropdown menu. Administrators have the flexibility to assign multiple ports and protocols to each application.
  Note: When HTTPS is the chosen protocol, administrators should specify the Domain Name rather than the IP address. The external domain name will be automatically populated.
• External Domain Name: Enter the external domain name. This domain name will be accessed directly by end users through the user portal.
• App Connector Group: Choose the relevant App Connector Group from the dropdown menu.
• Tags: Assign any relevant tags that apply to the application.

2. Additional Configuration (Optional)

• You have the option to configure the following additional parameters based on your requirements:
  • Sub-Domain Name: Utilize sub-domain names to enhance application structuring and organization.
    An application accessible through the parent domain could be redirected to another domain internally. These internal redirects do not get accessed through the Seqrite Universal Agent unless explicitly configured in the sub-domain section of the additional parameters. 

    In order to securely access all the domains of the parent domain through the ZTNA agent, add these domains to the sub-domain section.  

    For example:
    If we access the website https://documetation-example.com and the website loads and provides URLs to retrieve images from another website, https://documentaiton-images.com. In this scenario, the application URL would be https://documentation-example.com and the sub-domain would be https://documetation-images.com.

  • Protocol: Determine the communication protocol to be employed for data transfer.
  • Port Value: Establish the port value for streamlined data routing and connectivity.
• User Portal Settings: Customize access controls and personalize the user experience with the following options.
  • Lock Port Value: Secure a specific port number to prevent unauthorized changes.
    The user would connect to the port configured in the application and not a random port. For example, if the admin configured the application for port “8080” then the user would access the application on the same port. Without the Lock Port Value configuration, the user could connect to a random port (for example: 10450 and then internally it would redirect to the application port 8080).
  • Auto-Connect: Enable automatic connection establishment for user convenience.
    On successful end-user authentication, the application connection will be automatically established for user convenience.
  • Hide App on User Portal: Simplify the user experience by concealing the applications for which the Auto-Connect option is enabled within the user portal.
    This is an advanced configuration and should be done only when the end users have clear awareness of the accessible applications.

3. Advanced HTTPS Settings

• Enable HTTP/2
  With HTTP/2, loading times for websites are enhanced by reducing the latency and overhead associated with multiple requests.
• Bypass Authentication
  Bypass Authentication lets you get into apps directly without needing to log in through the user portal. You can get a complete overview of all the applications with Bypass Authentication enabled by accessing the WAF section on the Dashboard Page.

  Note ☛ Access to the Bypass Authentication option is exclusive to users who have purchased the add-on for either Enterprise or Standard licenses.

• Relative URL Path
  If the selected protocol is either HTTP or HTTPS, you must install the plugin before using relative paths in the application. After updating the relative path in the application, refresh the portal, reconnect, and changes will appear. Relative paths in logged-in agent apps are blocked when accessed, but not if logged in another tab.
• Default Landing Path
  The default landing path for an application refers to the initial page or screen that users encounter when they first access the application. With the default landing path set and Restricted Access Path enabled, users are limited to accessing only the landing path and are restricted from accessing other paths within the application domain. ZTNA provides built-in support for a default landing path, for cases where an application’s landing page is hosted elsewhere.

  Note ☛ The Restricted Access Path option is exclusively supported for the Default Landing Path.

Note ☛
For the Agent Based Apps the supported protocols are HTTP, HTTPS, RDP, SSH, Telnet, SMB, VNC, SFTP, FTP, and SCP.

Note ☛
Presently, in order to establish a connection with the SMB app on Windows OS, it is necessary to stop and disable the server services, followed by a reboot of the device.

Note ☛
After upgrading from ZTNA 2.2.4 to ZTNA 2.3.0, it is necessary to upgrade the agent to version 1.10.x during the downtime. If the customer’s agent version is 1.9.x or earlier, agent-based web or legacy applications (such as SSH) may fail to reconnect. In such cases, the customer must manually restart the ZTNA agent to restore connectivity to these applications. Automatic reconnection occurs only if the agent-based applications are configured for “Auto Connect”.

Setting Up Network Apps

To configure network applications, provide the following application details:


1. Application Details

Field	Description
Data Traffic	Select the direction of data traffic.
	Upstream	Upstream denotes data flowing from user endpoints to application servers. Select this option if you want to manage outgoing traffic from the application.
	Downstream	Downstream denotes data flowing from application servers to user endpoints. Choose this option if you need to manage incoming traffic to the application.
	Both	If you want to manage both incoming and outgoing traffic opt for this option.

Choose from IP ranges, single IP addresses, or entire subnets, and manage both TCP and UDP protocols across multiple ports. Simplify your admin tasks with ease.
Tags	Enter the tags applicable to the application.

Considerations for setting up network applications with TCP-UDP protocols

• Network Settings in Sites: In a specific scenario where UDP applications are being configured, it's essential to also establish TCP applications. This is because TCP is initially used to establish a connection, followed by a transition to UDP for communication. Moreover, for UDP applications to operate, virtual IP pools are utilized to dynamically assign IP addresses to agent devices accessing network applications. Each Seqrite ZTNA Agent will be allocated a singular IP address from the virtual IP pool for accessing network-based applications.
• App Connector Settings: For seamless access to UDP applications, ensure the App Connector is correctly installed and connected. Configure the LAN Subnet field within the app connector to enable access to diverse UDP applications. You have the option to enable or disable NAT according to your requirements. NAT facilitates the translation of private LAN IP addresses into public ones for internet communication, and vice versa, enhancing connectivity.

App Connector Configuration for Network Apps

Note ☛ For security reasons, the administrator must manually perform the following steps on the system where the app connector is installed.

If you are running the app connector on a Linux host system, you will need to ensure that your host OS meets the following requirements:

• Ubuntu 22.04 and above
• Kernel version > 4.5

Important Note ☛
You need to allow UDP port 1194 and 1195 in your host's firewall.

If you need to allow Ingress/Egress traffic from the app connector to your application, you will need to allow this traffic in your host machine's firewall. There are a couple of ways to achieve this:

For Debian-based systems using UFW:

If UFW is enabled in your host system, then you can allow traffic from and to the tun interface of the app connector using the following UFW commands:

• ufw route allow out on tun0: To allow traffic from the application to the app connector's Docker instance.
• ufw route allow in on tun0: To allow traffic from the app connector's Docker instance to the application.

For all other systems (including Debian-based) without UFW (i.e. UFW disabled/not present):

• The iptables utility should be installed in your Linux host with the help of the appropriate package manager.
  • For Debian-based systems, you can use the following command:

    apt-get install iptables

  • For RHEL-based systems, you can use the following command:

    yum install iptables

• After successfully installing the utility, run the following commands to allow traffic flow:
  • iptables -I FORWARD -i tun0 -j ACCEPT: To allow traffic from the app connector's Docker instance to the application.
  • iptables -I FORWARD -o tun0 -j ACCEPT: To allow traffic from the application to the app connector's Docker instance.

IP forwarding also needs to be enabled on Linux host systems. To check the current status of IP forwarding, run the following command:

cat /proc/sys/net/ipv4/ip_forward

If the return value is 0, then it indicates that forwarding is disabled. Enable it with the following command:

echo 1 > /proc/sys/net/ipv4/ip_forward

Important☛
All of the above commands require super-user privileges.

Connecting Network Apps from macOS System

When connecting network applications from a macOS system, you may encounter the following pop-ups. To proceed, simply click “OK”.
