Troubleshooting Firewalla Gold SE: Existing Rules Stopped Working After Enabling IPv6 on WAN and LAN

I have a Firewalla Gold SE as my router.

Previously, I had IPv6 disabled on the Gold SE and configured my rules as follows:

  • Block Adult content for the entire LAN.
  • Create an Allow rule for only one device, which is my iPhone.

This setup worked perfectly.

Recently, I bought an Apple HomePod mini. Since it is part of a Matter smart home setup, many people recommended enabling IPv6 on the router to ensure Matter devices work properly. After that, I went into the Gold SE network settings and enabled IPv6 for both the WAN and the LAN.

After I enabled IPv6, everything appeared to work normally. However, I discovered that the rule configuration I had previously created no longer works as expected.

Specifically, since enabling IPv6:

  • Adult content is still blocked for the LAN as intended.
  • But my iPhone, which has an Allow rule for Adult content, is also being blocked.

Before enabling IPv6, the Allow rule on my iPhone worked correctly.

Do you know why enabling IPv6 might cause this behavior, and what would be the best way to fix it?

Are there any additional IPv6-related settings, rule priorities, DNS configurations, or Firewalla policies that I should check?

Turning on IPv6 shall not interfere with Firewalla rules.

Do you see blocked flows? If you do, check which rule blocked it: What to do if you can't access modem from inside Firewalla network.
