What does the AWS network firewall service quota mean? AWS stands for Amazon Web Service and is one of the most comprehensive and broadly adopted cloud platforms.
How does AWS need a network firewall service? Let’s find out below.
What Is AWS Network Firewall Service Quota?
The AWS network firewall service quota is a set of rules and permissions that allow or deny the flow of traffic that passes through the Firewall. Also, the Firewall is a security tool that protects the AWS resources.
It acts as a filter to allow or block the incoming or outgoing traffic in the network. AWS network firewall has a limit on the amount of data it can scan.
So this data limit is called the AWS network firewall quota. If you breach this quota your account will be suspended until you update your account with a new quota.
How Does The AWS Network Firewall Service Work?
The Network Firewall maintains three tables for state information:
1: The state information for all the virtual services (VIPs) in your account
2: The state information for all the security group rules in your account
3: The state information for all the IP addresses in your account
What Are The Set Of Rules?
All the rules that are set in the Firewall are represented as a set of rules. A rule consists of a source IP address with a destination IP address and a protocol.
For example, if you want to allow only your address and block all other traffic you can add this rule to the firewall. If you want to allow both your address and any other address on the Internet.
Then you can use 0.0.0.0/0 for your source IP address and 0.0.0.0/0 for the destination IP address. The following table shows all the possible values for the source and destination IP addresses.
What Are The Limitations Of The AWS Network Firewall?
The AWS network firewall cannot be used to filter traffic by a security group or an EC2 instance. But it can be used to filter traffic between instances because they are part of the same network.
You can also use network security groups or EC2 instances. Or both for filtering traffic between instances because they are part of the same network.
How To Copy Your AWS Network Firewall Service?
You can copy your network firewall service quota. There are two ways to do this. You can use the AWS command-line interface or the AWS billing console.
If you use either of these methods, the Firewall configuration is transferred to a new subnet. So, to transfer configuration information from one subnet to another subnet.
Also, you must have a large network firewall service quota. If your subnets are in different regions then you need to specify a region when using the CLI or console to move configuration information from one subnet to another.
So this is because the AWS network firewall service quota is different for each region.
What Is The Minimum And Maximum Range Of The AWS Network Firewall Service?
First of all, let us tell you about the maximum and minimum range for the AWS network firewall service. The maximum quota is 5 TBs and it can be used for more than 9000 IP addresses in a single subnet.
So this means that you can have more than 9000 IP addresses in your subnets connected to the same VPN connection. The minimum quota limit is 10 MBs and it can be used for only 2 IP addresses in a single subnet.
So this means that you cannot use less than 10 MBs for a single subnet that consists of 2 IP addresses. It is because there is no such minimum limit for an IP address in a single subnet.
