My brother and I have been trying to play Minecraft together for a long time, but have never been successful. We have always run into some error message, no matter what we tried. I have recently purchased a PC that does not yet have our family blocker software (Integard) installed on it. On it, I found that I was finally able to connect to Minecraft Realms. However, my brother still cannot.

Because of this, we believe that the problem lies with Integard, the Internet Blocker application installed on our computers (except mine). To prove this, our parents temporarily disabled Integard, and he was able to successfully connect to the Realm. However, when the blocker was renabled, he again hit the Connection Blocked error message.

Does anyone know how to allow Minecraft through Integard, or a similar blocker? There is a list of allowed programs, which Minecraft is now on, but I'm not sure if this will work. Let me know if anyone has run into this before, or knows how to fix it. Also, is there a port number that Minecraft Realms runs through? If so, I could probably let it through. Thanks!

    I'm voting to close this question as off-topic because it is about disabling a third party program, not a game configuration or gameplay issue.

    I'm reopening this question because the port information is very useful for future visitors, and you're not really specifically asking about your software, but about any general firewall software. While we can't help configure specific softwares, this question and answer do have useful information. Aug 14, 2015 at 13:53

    @Frank was right. This question is purely about configuration of a third-party program, and has nothing to do with gaming. It should be closed as off-topic.

    I'm voting to close this question as off-topic because is a problem with 3rd party software and not the game itself.

I finally figured out what the problem was just now. It turns out that the Realms are allowed through Windows Firewall with no problem; rather, the problem came from Integard's Firewall. To fix this, I have to allow port 25565 through the Integard Firewall, and everything seems to be working.


I personally have not used Integard and cannot find resources for it online. However I can provide details for how Minecraft Realms connects and where the problem might be.

Based on the screenshots I can find, you should be able to configure Integard to not block Minecraft. You may, however, run into issues specifically that Minecraft is run under the java process. I would recommend trying to configure Minecraft to have no internet restrictions.


Here is a screenshot showing how I configure my Firewall to not block Minecraft. I don't know wether this will help but I figured I'd attach it.

  • Yeah, finding resources about Integard is impossible...I wonder if they no longer provide support? I have already tried fully disabling the Firewall, but to no avail. However, when Integard is disabled he is able to connect... Oh well, I'll keep trying :)

  • Thanks Ezekiel. Read my update (answer) for details of what happened. It was a firewall issue, just not Windows :)
