Pick one of two modes: no tool — change the computer's system proxy or delegate to your AI; or with a tool — from the official extension to common market tools. Same host and credentials for both.
A Proxy302 account and one proxy asset in a usable state (any type). Sign in at proxy302.com and open the workbench; the resource card showing "Generated and ready to copy" means you are set. No asset yet? Buy residential traffic or a static ISP line first.
Then pick a mode: without a connection tool (system proxy, terminal, code — or hand it to your AI), or with a connection tool (our extension and helper tool, plus common tools like SwitchyOmega, Proxifier and antidetect browsers). Both modes use the same credentials and you can switch anytime.

| Criterion | When to pick it | Typical practice |
|---|---|---|
| Without a connection tool | You want the whole computer, a terminal or specific code to go through the proxy; do it yourself or hand a ready instruction to your AI | System proxy settings, a curl config file, proxy options in your program |
| With a connection tool | You want one-click switching, per-site or per-app routing, multi-account isolation, or you are on a restricted network | Official browser extension, helper tool, SwitchyOmega / Proxifier / antidetect browsers |
The credentials are always the workbench resource card ones: host + username + password, port by line protocol (HTTP 2222, SOCKS5 3333).
With one set of credentials (host, username and password from the workbench resource card) you can connect without installing anything: set the system proxy for the whole machine, hit the gateway with curl, or pass proxy options in code. In a hurry? Send the instruction below, together with your credentials, to your AI assistant and let it do the work.

Please switch this computer's proxy to Proxy302:
1. On Windows open "Settings → Network & Internet → Proxy → Manual proxy setup",
set the address to proxy.proxy302.com and the port to 2222.
On macOS open "System Settings → Network → Details → Proxies → Web Proxy",
fill the same values and enter the credentials in the authentication fields.
2. Proxy username "your-username", password "your-password"
(from the proxy302.com workbench resource card — "Copy all").
3. Visit https://ipinfo.io/json afterwards and read me the exit IP and country.
4. If my line is SOCKS5, use port 3333 instead.Send this plus your credentials to any AI assistant and it can do the setup and verification for you; on Windows the browser shows a proxy sign-in dialog on the first request, once.
Windows: "Settings → Network & Internet → Proxy", turn on "Use a proxy server", address proxy.proxy302.com, port 2222. macOS: "System Settings → Network → Details → Proxies → Web Proxy", same address and port; username and password go straight into the authentication fields.
Expected result: The system proxy switch is on.
The Windows system proxy has no credential fields: on the first page request the browser shows a proxy sign-in dialog — enter the username and password from the resource card once. macOS will not ask again after you filled them in Settings.
Expected result: Asked once, then never again.
Open ipinfo.io; the IP and country shown are the proxy exit. They match the line you bought, the proxy is working.
Expected result: Exit country matches your line.
Before continuing: The system proxy applies to the whole machine — turn it off when you stop using it, or every app waits on a dead proxy when the network drops.
Create an empty proxy302.conf and restrict it to your own user before writing credentials (POSIX: touch proxy302.conf && chmod 600 proxy302.conf; Windows: restrict file permissions first). Then copy the block below and replace the placeholders. Keep passwords out of shell history and process arguments.
Expected result: proxy302.conf is in place and readable via --config.
In the same directory run curl -q --noproxy "" --config proxy302.conf https://ipinfo.io/json. -q ignores curlrc and --noproxy "" overrides target bypass variables. Check the returned exit IP and country against the line you selected.
Expected result: JSON returns; country matches the line you bought.
Run curl -q --proxy "" https://ipinfo.io/json as the direct control; it ignores curlrc and proxy environment variables. Compare both results and check the client configuration and recorded usage. An IP difference is useful evidence, but alone does not prove the route.
Expected result: Record both exits; investigate identical or unexpected results.

proxy = "http://proxy.proxy302.com:2222"
proxy-user = "your-username:your-password"For SOCKS5 replace the whole proxy value with socks5h://proxy.proxy302.com:3333, including the scheme. Use the exact username and password from your resource card, separated by a colon.

curl -q --noproxy "" --config proxy302.conf https://ipinfo.io/json
curl -q --proxy "" https://ipinfo.io/jsonThe first command selects the configured proxy; the second explicitly disables proxies. Compare ip and country. On Windows run these commands in Command Prompt (cmd.exe); older Windows PowerShell drops empty quoted arguments, so naming curl.exe alone is not enough.

| Criterion | Response | Notes |
|---|---|---|
| Proxied request | ip, city and country are the proxy exit | country should match the region of the line you bought. |
| Direct control | ip, city and country are your local exit | A difference is a useful signal; also verify client settings and usage. |
| Both identical | Check for bypass or a shared exit; equality alone is inconclusive. | Follow the "exit IP never changes" row in the table below. |
Read from the ipinfo.io response; different IP databases may locate the same exit slightly differently, so compare before and after within the same service.

| Criterion | How to choose | Port and notes |
|---|---|---|
| HTTP proxy | proxy.proxy302.com:2222 | The default for browsers, extensions and most tools; simplest to configure. |
| SOCKS5 | proxy.proxy302.com:3333 | Prefer it when the tool supports it. In curl, socks5 resolves DNS locally, socks5h delegates to the proxy. |
| Reaching HTTPS sites | Both protocols work | An HTTP proxy tunnels HTTPS via CONNECT; curl or your client verifies the target server certificate. |
Both ports live on the same gateway host; pick by your line's protocol.
Host, username and password belong to the asset itself: they change when you switch lines, regenerate or expire, so always trust what the workbench resource card shows now.
Give the credentials only to tools that need the proxy; never commit them to repositories, chats or script comments. When you keep proxy302.conf by hand, restrict the file to your own user (chmod 600 on POSIX, remove other users in the file properties on Windows) and delete it when done.
Expired or disabled assets cannot connect. Prepaid traffic uses the selected line quota; wallet PAYG uses the wallet balance and the supported billing mode. If credentials may have leaked, review usage and asset status before changing the line.
Tools solve three things: one-click switching, per-site or per-app routing, and multi-account isolation. Our own tools are the browser extension (simplest) and the helper tool (restricted networks); common market tools such as SwitchyOmega, Proxifier and antidetect browsers like AdsPower all take the same credentials.
Grab the package from "Downloads and setup" at the bottom of this page. Chrome users unzip it, open chrome://extensions, enable "Developer mode", click "Load unpacked" and select the unzipped folder; 360 browser users install the .crx directly. The Proxy302 icon appears in the toolbar when done.
Expected result: The Proxy302 icon is in your toolbar.
Click the icon to open the popup, click "Log in to your account" and finish signing in on the page that opens. Back in the extension your assets appear automatically — no host, username or password to type.
Expected result: The popup shows your account and assets.
Dynamic lines pick country/state in the popup and click connect; static lines select the asset. The popup shows the live exit IP — when the region matches your choice, the proxy is already working.
Expected result: The exit IP shows the selected region.
On some networks the extension cannot connect directly. Download the helper tool for your system from the bottom of this page, keep it running in the background, then open the extension settings and tick "Use helper tool" — the local IP is filled in automatically. The help center has illustrated steps per browser.
Scroll horizontally with the arrow keys to read all content.
| Criterion | What it is good at | How to fill it |
|---|---|---|
| SwitchyOmega (browser extension) | Per-site routing with one-click profile switching | New profile: proxy server HTTP proxy.proxy302.com:2222 (SOCKS5 uses 3333), credentials in the auth fields |
| Proxifier (Windows / Mac) | Route chosen apps through the proxy, leave the rest direct | Add a server in the profile with host, port and credentials, then add rules picking the apps |
| Antidetect browsers (AdsPower, BitBrowser, Hubstudio, …) | Multi-account isolation, one IP per account | Paste host, username and password into the browser profile's proxy settings |
Tool interfaces vary by version; follow each tool's official guide. The credentials are always the workbench resource card ones.
Scroll horizontally with the arrow keys to read all content.
| Criterion | Recommended path | Where to go |
|---|---|---|
| Whole computer through the proxy | System proxy settings, or hand the ready instruction to your AI | Mode one above |
| Terminal and scripts | curl through proxy302.conf | The command-line section above |
| Code and automation (Playwright, Selenium, requests) | Proxy options in your program; SOCKS5 uses 3333 | Scene pages |
| One-click browser switching, per-site routing | Official extension or SwitchyOmega | Mode two above |
| Multi-account, antidetect browsers | One IP per account; credentials into the profile proxy settings | The common-tools table below |
Every destination above is an existing on-site page. One port rule: HTTP lines 2222, SOCKS5 lines 3333.
If you write code, continue with the Playwright and Selenium scene pages; compare lines before buying if you are still deciding; the extension and desktop helper tools are under "Downloads and setup" at the bottom of this page, with per-browser illustrated steps in the help center.
Check: Whether you are on a non-overseas network (the helper tool is required) and whether another proxy extension is running (they can conflict).
Next action: Run the helper tool and tick "Use helper tool" in the extension settings; disable other proxy extensions and retry.
Check: Some apps ignore system proxy settings or carry their own network configuration.
Next action: Fill the proxy in that app's own network settings, or take it over per-app with Proxifier.
Check: Whether the credentials were copied whole (missing characters or stray spaces cause 407) and whether the asset expired or ran out of traffic.
Next action: Copy again with "Copy all" on the resource card and re-check asset status and remaining traffic.
Stop when: Do not hammer retries on 407; confirm credentials and asset state first.
Check: Match the protocol and port: HTTP 2222, SOCKS5 3333. no_proxy / NO_PROXY matches the target (here ipinfo.io), not the gateway.
Next action: Use the correct full proxy URL and the explicit bypass-control options shown above, then retry.
Check: Whether requests actually go through the proxy: an extension rule that misses, or code that never passes the proxy option to the real client, silently goes direct.
Next action: Locate it with the step-4 comparison and confirm the client really uses the proxy.
Check: For prepaid traffic check the selected line quota; for wallet PAYG check wallet balance and whether that product supports PAYG. These are separate funding sources.
Next action: Confirm the selected billing mode and its available funds before purchasing more traffic or topping up.
No. Browser users are done after the three extension steps; the command line is only how developers verify the gateway and write scripts.
Keep one active at a time. Two stacked proxy layers easily detour or fight over traffic; use Proxifier for per-app routing or SwitchyOmega for per-site routing.
Follow the line's protocol: HTTP proxy uses 2222, SOCKS5 uses 3333. When a tool supports both, prefer SOCKS5; see the curl manual on socks5 versus socks5h for where DNS is resolved.
Sign in at proxy302.com and open the workbench: the resource card shows host and username in plain text, masks the password, and "Copy all" grabs everything at once.
Command-line arguments persist in shell history and process listings; a --config file can be limited to your own user and deleted after use.
The credential belongs to the asset itself; concurrency and reuse limits follow the purchase page and line notes. For multi-account operations plan one IP per account.
