Verizon 5G Home Internet: IP Passthrough & Own Router Setup

Updated 2026-10-29 • By Marcus Vance, CCNA (Senior Network Engineer)

To use your own router with Verizon 5G Home Internet, log into the gateway at http://192.168.0.1, navigate to Advanced → Network Settings → WAN, and enable IP Passthrough on LAN Port 1. Unlike T-Mobile, Verizon provides a real routable public WAN IPv4 address, eliminating Double NAT and providing Open NAT for gaming and port forwarding.

Verizon 5G Home Internet Architecture: Why It Beats Other Wireless Carriers

Delivered over Verizon's mid-band 5G Ultra Wideband (C-Band, 3.7 GHz n77) and high-band mmWave spectrum, Verizon 5G Home Internet delivers download speeds ranging from 300 Mbps to 1,000 Mbps with significantly lower latency than satellite or legacy LTE.

For home networking enthusiasts and IT professionals, Verizon offers a massive technical advantage over T-Mobile: its gateways natively support true IP Passthrough. In addition, rather than forcing all traffic through restrictive 464XLAT CGNAT tunnels, Verizon provisions subscribers with a real, globally routable public IPv4 address (typically in the 174.x.x.x or 70.x.x.x range) alongside a native /56 IPv6 prefix.

When configured in IP Passthrough mode, the Verizon gateway disables its internal NAT routing table, shuts down its Wi-Fi radios, and bridges the cellular connection directly to the WAN port of your ASUS, UniFi, pfSense, or mesh Wi-Fi system. You achieve a pure single-NAT network with full port forwarding and Open NAT gaming capabilities.

Step-by-Step: Enabling IP Passthrough on ARC-XCI55AX & WNC-CR200A

Before beginning, disconnect all Ethernet cables from the Verizon gateway. Connect a single PC or laptop directly to LAN Port 1 on the back of the gateway using a Cat6 cable and disable your PC's Wi-Fi. Follow these exact steps:

1. Open your browser and navigate to http://192.168.0.1. Log in using the Admin Password printed on the sticker on the bottom of the gateway.
2. Navigate to the Advanced tab located in the top navigation bar.
3. In the left-hand sidebar, click Network Settings → WAN (or LAN → IP Passthrough depending on firmware build).
4. Locate the IP Passthrough setting. Toggle the switch to Enabled.
5. Ensure LAN Port 1 is designated as the Passthrough port.
6. Click Save Changes. The gateway will display a warning that Wi-Fi radios will be disabled and local DHCP will shut down on Port 1. Confirm and allow the gateway to reboot (this takes approximately 2 to 3 minutes).

Once the gateway reboots, its status light will turn solid white. LAN Port 1 is now a transparent bridge feeding public WAN packets directly to whatever hardware is plugged into it.

Configuring Your Third-Party Router WAN Port

Now that the gateway is bridged, connect an Ethernet cable from LAN Port 1 of the Verizon Gateway into the WAN port of your third-party router:

Step 1: Check Local Subnet Collisions

The Verizon gateway maintains an internal recovery subnet at 192.168.0.1/24. If your third-party router also defaults to 192.168.0.1 (common on TP-Link and D-Link units), the WAN and LAN subnets will overlap and traffic will drop. In your router GUI, change your router's LAN IP to 192.168.1.1 or 192.168.50.1.

Step 2: Configure WAN Parameters

• WAN Connection Type: Select Automatic IP (DHCP).
• MTU: Leave at standard 1500 (Verizon C-Band supports full 1500-byte MTU without fragmentation).
• IPv6: Set IPv6 Connection Type to Native or DHCPv6 and enable Prefix Delegation.

Navigate to your router's status dashboard. You will see your router's WAN interface display a public IPv4 address directly from Verizon. You now have full control over port forwarding, WireGuard VPN servers, QoS, and dynamic DNS.

Re-accessing the Gateway GUI & Troubleshooting

After enabling IP Passthrough, subscribers often panic when typing 192.168.0.1 into their browser because the page fails to load. Use these verified engineering recovery steps:

• Accessing the GUI via LAN Port 2: When IP Passthrough is enabled on Port 1, the Verizon gateway's web management server remains active exclusively on LAN Port 2. To view 5G signal metrics (RSRP, RSRQ, SINR) or adjust settings, connect a laptop to Port 2, assign your laptop a static IP of 192.168.0.50 with subnet mask 255.255.255.0, and open http://192.168.0.1.
• Checking 5G Signal Health: In the gateway GUI under System Status → 5G Status, monitor your SINR (Signal-to-Interference-Plus-Noise Ratio). A healthy C-Band link requires an SINR of +10 dB or higher and an RSRP better than -95 dBm. If speeds drop, rotate the gateway 45 degrees near a window facing your local cell site.
• Restoring Factory Routing Mode: If you ever need to undo IP Passthrough and restore gateway Wi-Fi, locate the recessed Reset button on the bottom of the gateway and hold it down with a paperclip for 10 seconds.

Verizon 5G Home Gateway Models & IP Passthrough Capabilities

Verizon 5G Home Internet IP Passthrough Checklist

1. Verify your Verizon gateway model is an ARC-XCI55AX or WNC-CR200A cube.
2. Connect a PC directly to LAN Port 1 and log into http://192.168.0.1 with the sticker password.
3. Navigate to Advanced > Network Settings > WAN and toggle IP Passthrough to Enabled.
4. Connect Cat6 from Gateway Port 1 to your third-party router's WAN interface.
5. Verify your router's LAN subnet does not conflict with 192.168.0.1 (use 192.168.1.1 or 192.168.50.1).
6. Confirm your router WAN interface displays a public IPv4 address and test Open NAT on gaming consoles.

Frequently Asked Questions

Does Verizon 5G Home Internet use CGNAT like T-Mobile?

No. While T-Mobile uses strict 464XLAT CGNAT on all residential lines, Verizon assigns dynamic public IPv4 addresses across the vast majority of its 5G Home Internet footprint. This means when you enable IP Passthrough, your router gets a real public IP, allowing port forwarding and Open NAT gaming.

Why does my gateway status light stay red after enabling IP Passthrough?

A red or blinking yellow LED indicates loss of cellular signal, not an IP passthrough error. Unplug the power adapter for 30 seconds, reposition the gateway closer to an exterior window, and power it back up. Once it locks onto a 5G C-Band signal, the LED will turn solid white.

Can I use both LAN Port 1 and LAN Port 2 for internet devices after enabling IP Passthrough?

No. Once IP Passthrough is enabled, LAN Port 1 is dedicated strictly to bridging your WAN traffic to your third-party router. All household devices, switches, and access points must connect downstream from your third-party router. LAN Port 2 functions only as a local management access port.

Does enabling IP Passthrough affect my Verizon Wi-Fi security guarantees?

No. When IP Passthrough is enabled, your third-party router takes over all firewall duties. Enterprise routers (UniFi, pfSense, ASUS) provide superior stateful packet inspection, Intrusion Prevention (IPS/IDS), and local network isolation compared to carrier-provided gateways.
