The first is to use the local computer configuration option, which means that each computer will need to be configured individually. The second is to use Group Policy, which allows for a single instance of configuration, which will then target many computers. To use the local configuration option, you will use the Server Manager interface that we discussed earlier on in this article. You will need to know what you want to control, as the wizard will not automatically generate rules.
So, for example, you will need to know one or more of the following to create your rules: the program, port, allow or deny action, encryption requirements, and scope of the connection. You can see the wizard in Figure 4. Figure 4: Windows Firewall rule wizard. The other option, to use Group Policy, has a very similar wizard to that of the local option. The big difference is that Group Policy can have a single instance for the configuration, but that single instance can affect many computers.
After creating your new GPO, you will edit it by right-clicking on it and selecting Edit. There is another Windows Firewall with Advanced Security node under the original one, but once you expand past this node, you will see the standard Inbound, Outbound, and Connection Security rules.
Each of these has a wizard associated with it, just like the local version. The Windows Firewall has been an under-utilized tool for many years. The interface has been unfriendly, the configurations confusing, and the overall capabilities less than impressive. Your email address will not be published.

Since its inception, the Windows Server SP1 firewall has been a basic, inbound-only, host based, stateful firewall.
With Windows Server , the built-in firewall has been dramatically improved. Let's find out how the new advanced firewall can help you and how to configure it using the MMC snap-in. What this means is that they create a strong perimeter around their network with firewalls and IPS systems, protecting themselves from malicious attackers on the Internet.
However, if an attacker could penetrate the outer perimeter and gain access to the internal network, there would only be Windows authentication security to stop them from gaining access to the company's most valuable assets - their data.
This is because most IT Pros don't secure their servers with host-based firewalls. Why is that? We see host-based firewalls as being "more trouble than they are worth". After reading this article, I hope that many of you will take a second look at the Windows host-based firewall. With Windows Server , the host-based firewall is built in to Windows, is already installed, now has more features, and is now easier to configure.
Plus, it is really one of the best ways to secure a crucial infrastructure server. So, what can the Windows Server Advanced firewall do for you and how do you configure it? With the addition of being a bi-directional firewall, a better GUI, and advanced rules configuration, the Windows Advanced firewall is bordering on being as good as traditional host-based firewalls like ZoneAlarm Pro, for example.
I know that the first concern of any server admin in using a host-based firewall is: what if it prevents critical server infrastructure apps from functioning? While that is always a possibility with any security measure, WFAS will automatically configure new rules for any new server roles that are added to the server.
However, if you run any non-Microsoft applications on your server that need inbound network connectivity, you will have to create a new rule for that type of traffic.
By using the advanced windows firewall, you can better secure your servers from attack, your servers from attacking others, and really nail down what traffic is going in and out of your servers.

Active 9 years, 11 months ago. Viewed times. Just booted into a newly provisioned windows server r2 server. On the firewall side of things, it is disabled by default. This is a web server, so I need at minimum port 80, rdp port left open. I export the rules to a file. Improve this question.
