WatchGuard Firewall Installation and Configuration

I will be mentioning you about the installation steps of a Watchguard brand Firewall device from scratch, but first of all, I would like to mention what Firewall is and what it does for those who do not know or beginners in this essay.

What is a Firewall?

Firewall systems aim to control all incoming and outgoing Network traffic, pass it through certain filters, and stop harmful actions in a Network traffic. In this way, Network security is provided. It is a security mechanism that protects your devices and computers on internal Networks against attacks that may come from other external Networks (Internet), and controls Network traffic between internal and external Networks (LAN & WAN) according to certain rules.

Basically, the Firewall decides whether the packets coming to it on the Network can go to the addresses they need to reach (with predefined rules). Protection is provided by blocking the traffic that does not comply with rules specified on the firewall. Firewall systems are divided into hardware and software based. Software-based Firewall applications are generally installed on operating systems on Client or Server. Hardware-based Firewall devices are systems operating on special hardware. Firewall devices or software basically aim to protect the Network you are in against malicious traffic and attackers that may come from untrusted external Networks (WANs) such as the Internet.

While providing this protection, they control your Internet traffic by processing special rules specified on it. If Firewall detects Network traffic that is against your security policy, it provides a secure layer to prevent it from accessing your internal Network and blocks this traffic. Firewall devices create a special layer through which only permitted traffic can pass, and they work by controlling the level of communication between external Networks (WAN) and your corporate or home Network (LAN).

I will show the basic Firewall setup process on the Firewall with the brand and model of WatchGuard T15 in this essay.
You can access the product information of the WatchGuard T15 series Firewall device on the WatchGuard Firebox T15 page.
You can get information about all WatchGuard products from All WatchGuard Products page.  
 

Firewall Device Connection Configuration

1-  I would like to mention how a Firewall is located on the Network and how the device cable connections should be made at the most basic level before proceeding with the installation process. All Firewall devices, regardless of brand or model, basically have two basic ports, LAN and WAN.


WatchGuard FireBox

LAN Port is used for your Internal Network; WAN Port is used for your external Network.

According to this;
• Assuming you have a Modem, a telephone cable with RJ11 connector used for Internet is plugged in to the RJ11 Port on the Modem.
• It is connected to the WAN Port of your Firewall device with a CAT cable from any of the RJ45 Ports on the Modem.
• After this connection between the modem and the Firewall is made, it is connected to any ports on the switch with a CAT cable through LAN port of your Firewall. All computers and other Network devices in your Internal Network (LAN) are also connected to this Switch and taken under the Firewall security umbrella.

WatchGuard T15 Firewall Setup

After configuring the active device connections, it is time to configure the initial basic setup processes.

2- Thinking that you have a Modem in your hand, the first thing to do is to switch the Modem to Bridge Mode.

NOTE 1: Since Bridge Mode settings will vary depending on the brands and models of modems you use, you are suggested to make a research from Google on how to get your modem into Bridge Mode.

NOTE 2: At this point, the Internet connection will be lost.

3- A second CAT cable must be removed from the switch and attached to the Network Interface Card-NIC Port of the computer through which we will perform the installation.

4- Watchguard Firewall Default IP address is 10.0.1.1/24. This IP address is also defined as Default in the LAN Port of the Firewall. So we need to set an IP address from 10.0.1.0 Network ID to the Network Interface Card-NIC configuration of the computer. I entered the IP address 10.0.1.10/24 for the installation process.

NOTE 3: I suggest you to test the connection by pinging the IP address of 10.0.1.1 upon completing the IP address identification.

5- After all these physical preparation processes are completed, it is time to download the Watchguard System Manager application. The WatchGuard System Manager application is a tool that provides management and configuration without the need for both WatchGuard Firewall device setup and Firewall management Web Portal.

You can download the Watchguard System Manager application through official website of WatchGuard.

If you wish, you can also select the Send device feedback to WatchGuard option and send the information about the device to WatchGuard. I prefer not to select this checkbox.

WatchGuard Kurulumu

13- I am specifying how to configure the WAN connection type in the Configure the External interface of your device step. In this step;

PPPoE (Point-to-Point Protocol over Ethernet): This option is the option we specify the User Name and Password, previously defined in your modem (before configuring it to Bridge Mode) and given to you by your ISP.
Static IP Addressing: This option is the option where we will enter IP address, Subnetmask and Gateway information to be given to you in case you use Metro Ethernet or Radio Link (Radio Link) Internet service.

In this step, I am selecting the PPPoE option and clicking on the Next button and going to the next step.

WatchGuard Kurulumu

14- I am entering the User Name and Password information provided to you by your ISP in this step since I chose the PPPoE option in the previous step of Configure the External interface of your device. There is an important detail for the IP address in this area.

14.1- It will not make any difference whether we use Obtain an IP address automatically or Use a static IP address since we are using static IP. Whether we get the IP address automatically or log in manually, we will be using the same IP address as a result.

WatchGuard Kurulumu

25- I am clicking on the Policy Manager button marked in the picture below to access the Policy settings.

WatchGuard Kurulumu

26- We see the default Policies and open Ports when the Policy Manager is opened. Two Policies are important here. These, required for accessing to the Internet, are the HTTP-Proxy associated with Port 80 and HTTPS-Proxy Policies associated with Port 443, and again, by default, all clients in the Network environment are open to access the Internet. Afterwards, restrictions and other Policy configurations can be done according to the needs.

WatchGuard Kurulumu

27- It is possible to access the management panel of the Firewall device with the LAN IP address and default port number 8080 through a browser. NOTE 4: The settings made on the management panel are directly saved in the Firmware of the Firewall device. For this reason, I recommend you to use WatchGuard System Manager instead of the Management panel.

WatchGuard Kurulumu
