Weird Firewall Rule Causes My VPN To Not Connect

aborgraffiti

Windows Firewall keeps creating a rule over and over again, it blocks my VPN from connecting. I tried reseting my firewall but it still comes back. It's named "4jxr4b3r3du76ina39a98x8k2" and under remote address it say's "8000::/1" and "::/1". I've also tried deleting, editing, and disabling the rule but it comes back. I installed a firewall program a couple days ago that was supposed to monitor connections, idk if it could have caused this. I have already uninstalled it though.

I am using the Bitdefender firewall, but this sounded very familiar and I checked out my Windows firewall rules (not in use).  I have the same rule in my outbound rules.  I can feel my paranoia level rising.

I have the Windows Firewall disabled and PIA installed. Yet I have no such rule. Do you guys have IPv6 enabled on your network adapters? (No idea if that is related, but I have all IPv6 disabled.)

Yes it's the ipv6 protection no need to worry.The fact that they use windows firewall to do it is rather funny cause they don't even mention it and lots of us don't use windows firewall. Anw if you go to pia app and unclick ipv6 protection no such rule will be created. Now when you say it blocks the vpn it doesn't and there must be another reason it doesn't work for you.

Try resetting your adapter cause kill switch might have messed it. Go to network connection, find the adapter you use, right click and select properties, internet protocol version 4(tcp/ipv4) and click obtain ip automatically and obtain dns server automatically.

Also take note that PIA does *NOT* support IPv6 in any way. It is exclusively an IPv4 network infrastructure that they use. You can still use things like 6to4 and Teredo to use IPv6 within the IPv4 setup of the VPN, but I suggest disabling all IPv6 unless you actually need it.

As @user1234 said, I never saw this because I have no IPv6 capacity at all. And because of that, there was no need to block IPv6 leaks.

The rule literally blocks all IPv6 networking, regardless of what protocol is used for it. (Like Teredo tunneling an IPv6 packet onto and through an IPv4 network.)

In case you are wondering why PIA would block all IPv6, it is simply because all IPv6 leaks information that can and will be used to narrow down who exactly you are.

Good work team!

I also have IPv6 disabled completely within my system.  I'm guessing that when I did a clean install and reinstalled all of my programs that I did PIA before Bitdefender, therefor Windows firewall was still on and created the rule.

Hi, sorry, know this thread is old, but I have this in my firewall as well.  I have seen other forums where they claim this is malware.  Is this malware or is it related to PIA?  I have a relatively new install and run Kaspersky and Malwarebytes already and they haven't found anything.

Thanks for any information.

I can also confirm.. that if you are having issues accessing files between computers in your own network while PIA is on - if you turn the IPV6 leak protection off.. the 4jxr4b3r3du76ina39a98x8k2 firewall rule is not created.  When the firewall rule is not there your access to the network computers will return. Not sure what the 4jxr4b3r3du76ina39a98x8k2 rule was intended for .. but it sure does block access to network computers.
I hope turning this off doesn't leave me vulnerable   because is it more important that I can access my drives.
I would appreciate any information about this if available.  Thanks to anyone who has the answer in advance!

@Cleo123 Sounds like your local network may try to use IPv6. You may try disabling IPv6 on your adapters which might help to get an IPv4 only network, but otherwise you're going to leak IPv6 without it enabled. If you don't have IPv6 internet you should be fine with just leaving IPv6 protection off.
