System Requirements & Supported Modems
This article covers everything your server and hardware need to be ready before installing the Proxidize platform. We recommend reviewing it before getting started to make sure your setup goes smoothly.
Operating System:
Proxidize runs on Linux only. The following are the only supported operating systems:
| OS | Supported Versions |
|---|---|
| Ubuntu | 20.04 LTS or 22.04 LTS |
| Raspberry Pi OS | Raspberry Pi 5 only |
Windows and other Linux distributions are not currently supported.
Hardware Requirements
Your server should meet or exceed the following minimum specifications:
| Component | Minimum Requirement |
|---|---|
| CPU | Dual-core processor (x86_64) |
| RAM | 4 GB |
| Storage | 32 GB available |
| Network | Wired Ethernet (required) |
⚠️ Wi-Fi is not supported. The Proxidize Linux agent must be installed on a server connected via Ethernet. Running it over Wi-Fi will cause instability and unpredictable connectivity issues. If your server is currently on Wi-Fi, switch to a wired connection before proceeding.
Running a larger setup?
For servers with 8 or more modems, we recommend 8 GB RAM. Storage needs will also grow depending on how many modems you're running and how long you retain logs.
Required Accessories
-
Externally powered USB hub
A powered hub is essential for connecting your USB modems. Unpowered hubs cannot reliably supply enough current to multiple modems simultaneously, which leads to dropped connections and modem instability. Do not skip this.
Supported USB Modems
Proxidize routes proxy traffic through USB modems that connect directly to a mobile carrier's network via SIM card. All Huawei HiLink models are fully supported, along with most ZTE models. The specific supported models are listed below.
💡 Stick to 4G modems. 3G-only modems typically deliver just 10–30% of their advertised speeds, which makes for a poor proxy experience. We don't recommend them.
Huawei Modems:
• E3372h, E3372sE8372h, E8278
• E303h, E353h
• E3276, E3276s
• E3272
• E3131, E3531, E3351, E3251
• E392, E397, E398
• E323S, UML397, EC3372
• K5005, K5007, K5150
• W5101
ZTE Modems:
• MF861, MF831, MF832G, MF832u, MF832s, MF833
• MF827, MF826, MF79, MF75
• MF820, MF820D, MF820T, MF820S2
• MF880
• MF821, MF821D, MF821S2
• MF822, MF823, MF825, MF825C
• MF170, MF730M, MF667
Picking the Right Modem for Your Region
Not all modems work everywhere. Different models support different cellular frequency bands, and using the wrong one for your region will result in weak signal or no connectivity at all.
| Region | Recommended Model |
|---|---|
| Europe, Africa, Asia (excl. China) | Huawei E3372h-153 or E3372h-320 |
| China | Huawei E3372h-607 (also compatible with Europe, Africa & Asia) |
| North & South America | Huawei E3372h-510 or E3372h-511 |
