![]() Service DefinitionsĬreating a new Service definition is slightly more straightforward, as there are no differences between the TCP, UDP, and TCP/UDP subcategories. Other Network definitions can be set in a similar fashion. For instance, if you have installed multiple NICs in your UTM and have separate networks for each, this might be a useful option for you. If you would like to use DNS internally, set your Hostname appropriately (and check “Reverse DNS” if you so desire). I tend to use the Comment field to mark the physical location of the device (who doesn’t need a computer in the bathroom?).įinally, Under “Advanced,” a specific Interface on the UTM can be set. Feel free to add wireless and wired MAC addresses for your object if your wired and wireless networks share the same IP range and you would like to set one IP per object regardless of connection type. Be sure to include colons between the octets (and click “Apply” when you are finished). Add a MAC address by pushing the ‘+’ symbol. The IPv4 Address field is for establishing an IP address for your object obviously, make sure it matches the schema of the network segment in which it will sit. If you choose to use your Sophos UTM as a DHCP server, you will use Host objects to define static IP addresses for the various devices and systems on your network. The various fields for a Host definition can be seen in the figure on the right. In this case, we’ll step through a “Host” object. Use the “Type” drop down box to select the subcategory under which your object will fall. By default, the page only lists ten definitions at a time, but there is a separate drop down box that can increase the results by factors of ten up to “All.” Network Definitions New Network ObjectĬlicking on the “+ New Network Definitions” button will open up a new frame in which parameters can be set for a new Network object. It is possible to search for specific definitions or filter out unwanted results using the provided drop down menu and search box at the top of the screen. Definitions OverviewĬlicking on “Network Definitions” on the left-hand side will drop you onto a page which lists all Network definitions including Networks, Hosts, DNS Hosts/Groups, and Groups. The Definitions Overview screen provides totals for existing Network and Service definitions and gives a breakdown of the subcategories for both. The first step is to click on “Definitions & Users” from the vertical menu on the left-hand side of the Dashboard as seen in the figure on the left. For convenience and ease-of-use, Sophos UTM comes with a myriad of pre-defined Network and Service objects, but you will inevitably want to add your own. In this post, we are going to focus in on Network and Service Definitions. ![]() It is possible to define a variety of objects within the UTM. This week, I’m going to cover establishing definitions and rules. Now, we’re going to start exploring the meat and potatoes of Sophos’ free UTM solution. Two weeks ago, we finished up the setup process. In the first and second posts in this series, we stepped through the installation of the Sophos UTM. UPDATE: Part 5 – SSL VPN is now available. ![]()
