How to Create a Low-Cost DIY 4G Proxy Network > 자유게시판

Setting up a low-cost cellular proxy network is easier than you think if you're willing to use readily available equipment and smart software choices. The goal is to create a system that can cycle across several mobile networks so that each web request appears to come from a different IP address. This is useful for web crawling, account automation, or testing location-based services without getting blocked.

First, http://hackmd.io collect your hardware components. You’ll need a batch of affordable mobile routers. Look for models like the Huawei E5573. These are often sold cheaply on eBay because people upgrade their personal hotspots. Aim for five to eight devices to start. You’ll also need a a multi-port USB charger and a low-latency Ethernet link for your master machine.

Next, acquire 4G SIM cards. Use prepaid SIM cards from different carriers if possible. This increases the diversity of your IP pool. You can buy these online in bulk for between $2 and $5. Make sure they are data-only SIM cards without SMS allowances to keep costs low. Load each with a 10GB–20GB tier, which should be enough for moderate web crawling.

Pair every router with an individual data plan and boot it. Configure each router to use a fixed LAN address so your central server can reliably maintain persistent connections. Most routers have a admin dashboard reachable via 192.168.1.1 or similar into a browser. Set a strong custom login for security.

Deploy a proxy forwarder on your central machine. Privoxy is a lightweight proxy solution that can be configured to rotate between multiple upstream proxies. Install it on a Raspberry Pi. Configure Squid to forward requests through each of your 4G routers. Each router acts as a distinct internet gateway. You’ll need to set up a proxy configuration array for each router in your squid.conf.

To automate IP cycling, use a a Python-based routing daemon every few requests. You can write a lightweight Python tool using httpx and asyncio to rotate between endpoints. Or use a tool like ProxyBroker to handle the load balancing. Test the setup by validating via iplocation.net and verifying the public IP refreshes reliably.

Monitor your cellular consumption. Cellular carriers often detect and restrict proxy behavior. If you notice slowdowns or blocks, increase delays between requests or add additional routers. Avoid high-volume requests. Wait at least 10–30 seconds between requests to stay avoid detection.

Ongoing upkeep is minimal. Reboot each router at regular weekly intervals to refresh the cellular connection. If one device loses signal, install a backup router. Keep backup hardware and SIMs on hand. You can increase capacity by integrating new LTE modems as your budget allows.

The beauty of this setup is its low cost. You can build a 5-router network for under two hundred dollars including everything needed to start. It’s not as fast or reliable as premium proxy providers, but it’s fully yours to manage. It’s also a great learning project if you want to understand how proxies, networks, and automation interact.

Adhere to responsible automation practices. Don’t violate privacy laws, breach website rules, or flood servers. Use your proxy farm for authorized research where you have permission. With meticulous tuning, your budget cellular proxy network can be a powerful and affordable tool.
