This book is the ideal companion for understanding, installing and setting up an OPNsense firewall.īuy online from Bod Buchshop or Amazon Īlso bundled with the OPNsense® Business Edition license as E-book. OPNsense accepts the challenge and meets these criteria in different ways. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure. They protect against known and new threats to computers and networks. Firewalls are a component of the security concept. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. No network is too insignificant to be spared by an attacker. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. Even the open-source domain is moving towards Next-Generation Firewalls. Simple packet filters are becoming a thing of the past. The SFOS license only limits you to 4 CPU cores and 6GB of ram (VERY GENEROUS!).Available Now! - 4th Edition! The complete 4th Edition of Practical OPNsense® by Markus Stubbig First off, the UTM9 home license limits you to 50 internal IPs (may be 100 now). But there are also compelling reasons to run SFOS at home over UTM9. That being said…SFOS IS the future for Sophos. (even though SG and XG hardware can run both UTM9 and SFOS) Unfortunately, due to marketing and so forth… SG is now synonymous with UTM9 and XG is synonymous with SFOS. You could “downgrade” and XG to UTM9 and “upgrade” an SG to SFOS. At this point, the SG and XG hardware was exactly the same…except for which OS was pre-installed. Once the “next generation” firewall OS was ready (SFOS), it was released on a new hardware platform…the XG. UTM (and ASG, before the Astaros were re-branded) was the hardware platform that exclusively ran UTM9 (and UTM8 previously). Basically, there are two firewall platforms… UTM9 and SFOS (Sophos Firewall OS). You learn how to secure access to your Sophos Firewall, test and validate it, and finally how to go live once you feel comfortable. There is so much confusion regarding the Sophos firewalls names/models/etc. Last update: Table of contents Secure administrator access to Sophos Firewall Test and validate Go live Add new services Getting started Follow these recommendations if you're new to Sophos Firewall. I used this Arctic Silver kit which includes cleaning solution and non-conductive thermal paste. Note: Many users of the Qotom devices have reported lower CPU temperatures by reapplying the thermal paste between the CPU and heat sink. Follow the Sophos XG Configuration Wizard. This occurs because your web browser does not have the Sophos XG SSL certificate.ġ0. You will receive a security/error message in regards to the website’s security certificates which you can ignore and continue browsing to the website. From your web browser, access the web GUI by browsing to ĩ. You can choose to skip the activation process and do it at a later time.Ĩ. Additionally, connecting your internet modem to Port 4 isn’t required unless you want to activate Sophos XG during the initial setup. The ports labeled 1-2-3-4 on the physical device are actually ports 1-3-4-2 within Sophos XG (which is technically eth0-eth2-eth3-eth1). The only reason Im looking to get rid of my current home network setup is that the 8 port switch doesnt have enough ports and I do want to turn on the IDS/IPS. Note: The Qotom Q355G4 network ports aren’t actually in the order as listed on the physical device. Connect the internet modem to Port 4 on the Q355G4 (this is actually ‘eth1’ within Sophos XG). Sophos XG will automatically assign an IP address as it has a DHCP server running by default. Connect a computer to Port 1 on the Q355G4 (this is ‘eth0’ within Sophos XG). At this point, Sophos XG is up and running and you only need to log in if you need to shut down the device or wish to configure Sophos XG from the console. After the device reboot, the setup process will continue eventually leading to a prompt asking for a password. Once the initial part of the installation is complete, you will be asked to remove the install media and reboot the device. This will force a boot to your USB drive.Ħ. Note: If ‘F10’ is not working, you can also go back into the BIOS and select ‘UEFI: ’ under ‘Save & Exit’ -> ‘Boot Override’. With the USB drive plugged in, press ‘F10’ during boot up and select the USB drive as your boot device. Note: Recommend setting ‘Restore From AC Power Loss’ option to automatically turn on your device after a power loss event.ĥ.
