ZTE T3000路由器静态IP、默认网关设置及DNS配置求助

Hey Anton, let's work through this step by step to get your router setup sorted—this is a common hiccup with multi-router configurations, so we'll fix it easily.

First, let's clear up the default gateway confusion:
Your ZTE T3000 is a secondary router connected to the ZTE MC889 (your primary 5G gateway). The default gateway for the T3000 has to be the LAN IP address of the MC889—this is how the T3000 sends traffic out to the internet through your 5G unit. It can't match the T3000's own IP (192.168.0.1) because that would create a routing loop, which is why the router blocks it.

How to find your MC889's LAN IP: #

• Temporarily disconnect the T3000 from the MC889, then connect your computer directly to one of the MC889's LAN ports.
• On Windows: Open Command Prompt and run ipconfig—look for the "Default Gateway" line under your active network adapter. That's the MC889's IP.
• On Mac/Linux: Open Terminal and run ip a (or ifconfig on older systems)—the default gateway will be listed as default via [IP].

Once you have that MC889 IP, here's your correct T3000 configuration:

• IP Address: Keep 192.168.0.1 (just make sure this IP isn't already used by the MC889 or another device—if it is, pick an unused one in the same subnet like 192.168.0.2)
• Subnet Mask: Leave 255.255.255.0 (this is standard for home network subnets)
• Default Gateway: Paste the MC889's LAN IP you found earlier (common defaults for ZTE gateways are 192.168.0.254 or 192.168.1.1, but use the actual IP from your check)
• Primary DNS: 192.168.0.107 (your PiHole—just confirm it's powered on and connected to the same network)
• Secondary DNS: 1.1.1.1 (Cloudflare's reliable public DNS, great as a fallback)

Save these settings, restart the T3000, then test connectivity: ping the MC889 IP, your PiHole, and a public site like google.com to make sure everything routes properly.

If you hit snags (like no internet access), double-check:

1. The MC889's LAN subnet matches the T3000's IP (e.g., if MC889 is on 192.168.1.x, adjust the T3000's IP to 192.168.1.x too)
2. No other device is using the IP you assigned to the T3000
3. Your PiHole is configured to accept DNS requests from your entire network
