+**Doing Double Nat on the Bell Home Hub 3000. Needs a second router.**
+<code>Understanding Double NAT Issues
+What is Double NAT?
+NAT (Network Address Translation) is what your router uses to share one public IP address among all the devices on your home network.
+Double NAT happens when two devices are both performing NAT at the same time.
+This is very common with ISP-provided gateways (like the Bell Home Hub 3000) + a second router.
+Typical setup that causes Double NAT:
+Internet → Bell Home Hub 3000 (NAT #1) → Your own router (NAT #2) → Devices
+Why Double NAT Causes Problems
+| Problem                        | Why it happens                              | Common Symptoms |
+|--------------------------------|---------------------------------------------|-----------------|
+| Port Forwarding fails      | Ports opened on the second router never reach the internet | Games, Plex, cameras, remote access don't work from outside |
+| UPnP / automatic port mapping fails | Devices can't properly request open ports | Consoles show Strict/Moderate NAT |
+| Online gaming issues       | Higher latency, can't host games, voice chat problems | "Strict NAT", can't join friends, lag |
+| Remote access broken       | Can't reach devices from outside your network | Security cameras, home servers, VPN |
+| Some apps fail            | Certain services detect multiple NATs      | Smart home devices, VoIP, some cloud services |
+| Slightly higher latency    | Traffic has to be translated twice         | Usually minor (1–5 ms) |
+How to Check if You Have Double NAT
+Log into your second router and look at the WAN IP address.
+If the WAN IP starts with:
+.168.x.x
+.x.x.x
+.16.x.x to 172.31.x.x
+   → You are behind Double NAT.
+Compare it with the public IP shown on sites like whatismyip.com.
+   If they are different → Double NAT confirmed.
+How to Fix Double NAT (Best Solutions)
+| Solution                    | Difficulty | Recommended? | Notes |
+|----------------------------|----------|--------------|-------|
+| Put Home Hub in Bridge Mode | Medium   | Best        | Ideal if available |
+| Use Advanced DMZ on Home Hub | Easy     | Very Good   | Common workaround on Bell HH3000/4000 |
+| Put second router in Access Point mode | Easy | Good     | Disables NAT on second router |
+| Cascade properly + port forward on both | Hard | Temporary | Works but messy |
+| Ask Bell for a public IP / Bridge mode | Easy | Best long-term | Sometimes available |
+Recommended Fix for Bell Home Hub 3000
+Most people use the Advanced DMZ method:
+Log into the Home Hub 3000 (192.168.2.1)
+Find Advanced DMZ or DMZ settings
+Put your second router’s MAC or IP into the Advanced DMZ
+On your second router, set the WAN connection to DHCP (obtain IP automatically)
+This effectively gives your second router a public IP and removes the Double NAT.
+</code>
+**exact step-by-step instructions for fixing Double NAT on the Bell Home Hub 3000**
+<code>
+Exact Step-by-Step Instructions: Fix Double NAT on Bell Home Hub 3000
+The best and most commonly used method is Advanced DMZ. This gives your second router a public IP address and eliminates Double NAT.
+Before You Start
+Have a computer connected to the Home Hub 3000 (wired is best).
+Know the MAC address of your second router’s WAN port (check the router’s status page or sticker).
+Connect an Ethernet cable from a LAN port on the Home Hub 3000 to the WAN port of your second router.
+Step-by-Step: Enable Advanced DMZ
+Open a web browser and go to:
+   http://192.168.2.1
+   (or try bell.ca/mymodem)
+Log in with the administrator password
+   (usually the serial number on the sticker on the back of the Home Hub 3000).
+Click Advanced tools and settings (or Advanced).
+Click DMZ on the left side.
+Turn DMZ ON.
+Find your second router in the list of devices (or manually enter its MAC address).
+Select your router and move it to the DMZ side (right side).
+Very important: Check the box or option that says Advanced DMZ (this is the key step — regular DMZ is not enough).
+Click Save or Apply.
+Reboot the Home Hub 3000 (unplug power for 30 seconds, then plug back in). Wait until it fully restarts (all lights normal).
+On your second router:
+    Set the WAN connection type to DHCP / Obtain IP automatically.
+    Do not enter PPPoE credentials.
+    Save and reboot the second router.
+After both devices restart, check the WAN IP on your second router.
+    It should now show a public IP address (not 192.168.x.x).
+Extra Recommendations
+Turn off Wi-Fi on the Home Hub 3000 to avoid interference (keep only one network if you still need it temporarily).
+Plug all your devices into your second router, not directly into the Home Hub.
+If Advanced DMZ becomes unstable later, toggle it Off → Save → On → Save, then reboot both devices.
+Would you like the alternative PPPoE Passthrough method as well (sometimes more stable)?
+</code>
+**alternative PPPoE Passthrough method**
+<code>Alternative Method: PPPoE Passthrough on Bell Home Hub 3000
+This method is often more stable than Advanced DMZ. Your second router authenticates directly with Bell using PPPoE, effectively bypassing the Home Hub’s NAT.
+What You Need
+Your Bell b1 username (starts with b1, e.g. b1xxxxxx)
+Your Bell PPPoE password
+  Find them in your MyBell account under Internet services, or call Bell support to retrieve/reset them.
+Step-by-Step Instructions
+Connect the hardware
+   Plug an Ethernet cable from a LAN port on the Home Hub 3000 into the WAN port of your second router.
+Log into your second router
+   Open its admin page (usually 192.168.1.1 or 192.168.50.1, etc.).
+Configure the WAN settings on your second router
+   Go to Internet / WAN settings.
+   Change Connection Type (or WAN Type) to PPPoE.
+   Enter:
+     Username: your b1xxxxxx username
+     Password: your Bell PPPoE password
+   Leave other settings (VLAN, MTU, etc.) at default unless your router requires VLAN 35 (most consumer routers do not need it when connected this way).
+   Save the settings.
+Optional but recommended on the Home Hub 3000
+   Log into 192.168.2.1.
+   Turn off the Home Hub’s Wi-Fi (Primary + Guest) to avoid interference.
+   You can leave DHCP enabled.
+Reboot both devices
+   Reboot the Home Hub 3000 first.
+   Then reboot your second router.
+Verify
+   On your second router’s status page, the WAN IP should now be a public IP address (not 192.168.x.x).
+   Test your internet connection.
+Advantages of PPPoE Passthrough
+Usually more stable than Advanced DMZ
+No need to keep toggling settings on the Home Hub
+Works well for most people
+Possible Drawbacks
+On very high-speed plans (1.5 Gbps+), some older routers may not achieve full speed due to PPPoE overhead.
+You must keep your b1 username and password up to date.
+Would you like me to also give you tips for specific router brands (ASUS, TP-Link, UniFi, etc.)?
