IPBlock is an advanced firewall and request filter that blocks unwanted traffic and mitigates DDoS attacks on real-world servers running on Windows Server and the major Linux distributions. With a few clicks of a mouse, IPBlock lets you take the following actions:

• Set up multiple additional firewall rules
• Set up multiple web-server filters in IIS (Apache and Nginx are coming soon)
• Create IP ranges based on specific filtering data, such as:

• Whitelist custom IP ranges and approved crawlers
• Automatically switch to a more restrictive blocking set in case of a DoS (denial of service) and DDoS (distributed denial of service) attack

How does it work? Let's say that our server runs an English-language website, and the vast majority of the audience comes from the US, Canada, and countries in Western Europe. If we examine the logs of our website, we will likely discover that a large portion of the requests are coming not from legitimate users, but from rogue spiders, exploits, and site scrapers originating in clouds and data centers all over the world. At the best, all this traffic is useless – at worst, it can be harmful to the site. The built-in firewall cannot filter it out. But IPBlock can.

All we need to do is to install IPBlock on our server, and then go to the customer portal on IPBlock.com. With a few clicks, we can create a custom IP-blocking set that includes, for example, all data centers

as well as any country that your services do not target.

Just to be safe, we can whitelist Google, Bing, and a few other search engines. We then create a rule for the web site ports, attach the newly created IP set, and push it to our server. Now, except for the ones we whitelisted, no server anywhere can access our website, and all traffic from countries of no interest to us will be blocked.

But that's not all. We can create a more restrictive set of blocks that includes every region other than the US, Canada, and Western Europe, all data centers except Google and Bing, and every known compromised computer in the world.

We then add this new set to our rule as an automatic failover in case our web traffic exceeds normal levels to an unusual degree. Now we have a server that will instantly block the majority of incoming packets in case of a DoS or DDoS attack.

IPBlock does not stop there. With multiple IP sets, firewall rules, and web server filters, the administrator can also:

• Create different rules for different websites, protocols, and ports (for example, open public website ports worldwide but restrict admin ports to a single country only)
• Block some traffic while redirecting other traffic
• Deploy the same rules and IP sets to multiple servers with a single click
• Monitor the status of blocking in real time

IPBlock has been officially approved and certified by Microsoft as a software ready for Windows Server 2016, 2019, and 2022. IPBlock software have been thoroughly tested to confirm its compatibility and adherence to Windows Server best practices.

And, of course, IPBlock updates its data and blocking sets automatically, so you can feel safe knowing that your server is always secure. At the same time, you'll save money by eliminating bandwidth and CPU waste on handling unwanted traffic.
