Using MizpahGuard with AT&T

AT&T’s newer gateways (BGW210 and BGW320) don’t have a DNS setting for the devices in your home. AT&T’s own name for bridge mode is IP Passthrough.

Option 1 — Whole home: IP Passthrough with your own router

  1. Connect to the gateway and open http://192.168.1.254; sign in with the Device Access Code printed on the gateway.
  2. Go to Firewall → IP Passthrough. Set Allocation Mode to Passthrough and Passthrough Mode to DHCPS-fixed, then choose your own router from the device list (by its MAC address). Save.
  3. Plug your router into the gateway and set DNS on your router to:74.208.171.84If the device also has an IPv6 DNS field, enter:2607:f1c0:f0da:1300::1
  4. Back in MizpahGuard setup, let it re-detect your home’s address and confirm it.
Menu names are from third-party guides for these gateways and can differ by firmware version. If you don’t see them, AT&T support can point you to IP Passthrough for your model. Older AT&T gateways (the Motorola NVG series) may still have a DNS field under Settings → LAN → DHCP.

More background: using your own router.

Option 2 — One device or browser at a time

Protect a browser, or set DNS on a device: iPhone / iPad / Mac, Android, Windows, game consoles.

How to tell it’s working

The quick test: on the device you just set up, open example.com. On an unprotected device you see a plain page titled “Example Domain”. On a device protected by MizpahGuard you see our “It’s working” page instead — it is blocked on purpose, for every household, so you can tell at a glance. (Your browser may show a certificate warning first, as it does for any blocked site; continue past it.)

You can also open your home’s Activity tab in MizpahGuard and look for the device’s browsing within a minute. If the test page doesn’t appear, the device is still using another DNS server — recheck the steps, or contact support from your dashboard and tell us your device and internet provider.
