Introduction

This guide provides detailed step-by-step instructions to upload, provision, install and configure the new Sophos XG Firewall in a ProfitBricks virtual Data Center (VDC).

Helium 4 and helium 3 are. Established an internet connection out to the Sophos servers through your WAN port; you must be able to receive an IP address through DHCP Register and activate your XG Firewall after a fresh installation When you try and access the Device Management user interface for the first time, you will see a security alert.

Prerequisites

Users tend to use the services of proxies to bypass Sophos XG Firewall's restrictive policies. It is required to block access to the proxies themselves. This article describes how to block unauthorized internet access by users through proxies. The following sections are covered. Configure IPsec remote access connections To allow remote access to your network through the Sophos Connect client using an IPsec connection, do as follows: To turn on IPsec remote access, click VPN IPsec (remote access) and select Enable. Specify the settings on the page and click Apply. My googlefu is failing as most hits are related to no Internet access at all, or threads that deal with this specific issue but no follow through. Yes, I know that no internet connectivity 'feature' can be disabled in the registry. Workstations can access that.txt file or whatever that 'feature' checks for on the Microsoft website.

This will provide you with

• An ISO image.
• A valid serial number.

Upload ISO image

1. Use a FTP Client, such as FileZilla, to upload the Sophos XG ISO to your ProfitBricks account using your DCD login credentials.
2. Upload the ISO into the 'iso-images' folder.
3. Once the internal processing of the image is finished you will receive an email.

Create or use virtual data center

Login in to the DCD and create a new data center or select an existing one.

Reserve IP Addresses

Since the firewall is a permanent device in your network, it is recommended to use a fixed IP address.

1. Open IP Manager from the top navigation bar.
2. Click on Reserve IPs, provide a name and set Number of IPs to 1. Make sure the correct region of your data center is selected.
3. Click the button Reserve IPs.

Create Jump Server Instance

Initial configuration of the Sophos XG needs to be done from a web page running on the XG. This web page is only accessible from the internal LAN interface of the XG and not from the public (internet) interface of the XG. In order to access the web page, a jump server, located in the same internal LAN as the XG, is therefore needed.

1. In your VDC, use a Composite Instance to create a Windows 2012 server which will be used as a jump server.
2. Use the default settings for the server configuration.
3. Select the ProfitBricks image windows-2012-r2-server as boot volume.
4. Increase storage size (Size in GB) to 15 in order to accommodate minimum requirement of Windows Server 2012 R2.
5. Provide a Password for the administrator account.
6. Attach the server to the Internet Access box.

Create Sophos XG Firewall Instance

1. Create the Sophos XG server using a composite instance.
2. Use the following settings for the server configuration (based on the recommended requirements by Sophos):
3. Cores: 2
4. RAM: 4
5. HDD size: 64 GB

Do not select any boot image. Sophos xg aws.

Select ISO Boot Device

1. Select the Sophos XG instance, go to the Inspector sidebar and select the Storage tab. Now click on Add CD-ROM.

2. In the Create New CD-ROM pop-up, click on No Image Selected, navigate to Own Images and select the previously uploaded Sophos XG ISO.

3. Leave Boot from Device unchecked

4. Click on Create CD-ROM Drive
5. When using the uploaded image for the first time, you will be asked to provide the operating system. Select Linux and confirm.

Configure Network

1. Connect the first network interface (NIC 0) of the XG with the second NIC (NIC 1) of the jump server.

2. Connect the second network interface (NIC 1) of the XG with internet access. Note: The interfaces on the XG need to be created in this exact sequence otherwise the further configuration will not work. The network topology should look like pictured below.

3. Select the jump server and in the Inspector sidebar, select the Network tab, go to NIC 1 and set the Primary IP in this private LAN to 172.16.16.10

4. Now select the Sophos XG server and in the Inspector sidebar select the Network tab, got to NIC 0, disable the DHCP option and set the Primary IP in this private LAN to 172.16.16.16

5. For the Primary IP of NIC 1 of the XG, select your previously reserved IP address.

Provisioning

Now provision all changes by clicking on the Provision button on the top of the designer or Provision xx changes in the Inspector sidebar. The background validation should contain no error or warnings. Click on Provision Now to finally provision all instances and their configurations.This process will take several minutes. The current status can be followed in the Inspector sidebar.

When all jobs have been provisioned a box will pop up letting you know provisioning has been completed successfully. Click the OK button.

Install Sophos XG Firewall

1. In the ProfitBricks DCD, select the Sophos XG instance.
2. In the Inspector sidebar, click the button Remote Console.
3. A new browser window should open. Click inside the window and type y and press enter. (Notice: The installer is configured to use a US keyboard layout.)

The installer will now format the empty storage volume, create a new file system, and install all necessary files. A progress indicator allows you to monitor the progress.

1. After all files have been installed, press y to reboot the firewall.

2. At this point, the system is running Sophos XG Firewall Software Appliance. After the first boot, the system will present details about the hardware configuration and prompt for a password. The default password is admin.

3. Accept the EULA by pressing a.

4. Per default, the Sophos XG assigns the IP address 172.16.16.16 to its first NIC. At this IP address the web based Admin Console is also accessible. In order to activate the firewall, an internet connection is required. Verify the network configuration before starting the actual web based configuration. Using the console, in the Main Menu select 1 for network configuration.

5. Select 1 for interface configuration.

6. Make sure that interface Port1 contains the IPv4 address 172.16.16.16. A gateway does not need to be configured. Press enter to continue.

7. Make sure that interface Port2 contains the reserved public IPv4 address assigned by the ProfitBricks DHCP server. This IP address should match the one displayed in DCD under the network setting of your Sophos instance. For external communication a gateway IP address must also be set. Again, this should be automatically assigned via the DHCP server.

8. If any of the IP addresses are not correct, press y on the following screen and enter the correct IP address.

Web-based Activation of Sophos XG

The web-based Admin Console of the Sophos XG is available at https://172.16.16.16:4444. Use the jump server to access this page.

1. Open a Remote Desktop Connection to the public IP address of the Windows jump server. You will find the public IP address in the NIC 0 Primary IP field in the Inspector sidebar after selecting the jump server in your VDC. Note: This IP address has been dynamically assigned and may change after a power off of the server.

2. Use your browser on the jump server, open https://172.16.16.16:4444 and log into the Admin Console using the default credentials username - admin and password - admin. You might need to wait a couple of minutes before the http server on the firewall is correctly loaded and the web page is accessible. The browser's certificate error can be safely ignored. (Note: It might be helpful to download Chrome on your Windows jump server or otherwise you need to lower all IE security settings to a minimum in order to properly use the Sophos Admin Console.)

3. When you now log in for the first time, you will need to activate your device. Enter a valid serial number you have received from Sophos. Then click on Activate Device.

4. Note: in some cases, the public IP address configured via DHCP is not persisted on the firewall. In this case, the activation will fail with the error message No internet connection. Check your internet connection as described in the product documentation. Go to Basic Setup, select Static as IP Assignment and provide the following information:

5. IP address: enter the reserved public IP address you assigned to NIC 1 of your Sophos instance
6. Subnet Mask: 255.255.255.0
7. Default Gateway: can also be found in the NIC 1 setting in DCD but is always the .1 of the subnet of your device.
8. DNS: 8.8.8.8 (public Google DNS)

and click on Save Changes.

1. Now try to activate the device once more.
2. After the successful activation, you will need to register your device. Click Register Device to initiate the registration process.

3. After clicking Register Device, you are redirected to the MySophos portal website. If you already have a MySophos account, click on Login. If you are a new user, sign up for a MySophos account after clicking on Create Sophos ID.

4. After successful login, click Continue on the next window.

5. After successful registration of the device, you need to synchronize license details with Sophos servers. Click Initiate License Synchronization to initiate the process.

6. If the license has been successfully synchronized, you will see the Welcome page. Start the Network Configuration Wizard by clicking on Click Here.

7. The wizards walks you through the steps to setup initial configuration of your Sophos XG Firewall so that you can begin creating your security policies.
