There are a few steps you can follow to set up a firewall on your broadband connection:
Type of firewall
Hardware firewalls: These are physical devices that sit between your home network and the internet. They can be standalone devices or they may be built into your router. Hardware firewalls are typically more secure than software firewalls because they are always on and cannot be turned off by malware.
To set up a hardware firewall, you will need to connect it to your router and configure it using the manufacturer's instructions. This will typically involve creating a set of rules that specify which types of traffic should be allowed or blocked.
Software firewalls: These are programs that run on your computer and can be turned on and off as needed. They can be effective at blocking unwanted traffic, but they are only as secure as the computer they are installed on. If the computer becomes infected with malware, the firewall may be disabled.
To set up a software firewall, you will need to install the firewall program on your computer and configure it using the manufacturer's instructions. This will typically involve creating a set of rules that specify which types of traffic should be allowed or blocked.
Firewall settings
Most firewalls have a set of rules that specify which types of traffic should be allowed or blocked. These rules can be based on factors such as the type of traffic (e.g. web traffic, email traffic), the source or destination of the traffic (e.g. a specific IP address or domain name), and the port number being used.
To configure your firewall, you will need to create a set of rules that reflects your desired level of security. For example, you may want to block all traffic from unknown sources, or you may want to allow certain types of traffic (e.g. web traffic) while blocking others (e.g. peer-to-peer file sharing).

Test firewall
After you have set up your firewall, it is a good idea to test it to make sure it is working correctly. You can do this by trying to access a website that you have blocked, or by using a network scanning tool to see if your firewall is blocking unwanted traffic.
Up to date
It is important to keep your firewall up to date to ensure that it is able to protect you from new threats. Most firewalls will have an option to check for updates and install them automatically. You should make sure to keep your firewall updated to ensure that it is able to protect you from the latest threats.
I hope this helps! If you have any other questions, please don't hesitate to ask.
