# Tun2Socks Proxy Setup Guide

> Tun2Socks is a free app available on Android devices and tunnels connections for your apps.

<Warning>
  Tun2Socks is not available on the Apple **iPhone**.
</Warning>

## Getting Started

Before proceeding, ensure you have:

* No other VPN or proxy active.
* The **proxy endpoint** and **port** (e.g., `us.decodo.com:10101`).
* Your **proxy username** and **password** (or a **whitelisted IP** set).

<Tip>
  **Proxy Guides**

  Learn how to find **proxy details** in your dashboard for each proxy type [**here**](https://help.decodo.com/docs/proxy-quick-start-guides).
</Tip>

## Android Setup

<Steps>
  <Step>
    Download the app from [**the Play Store**](https://play.google.com/store/apps/details?id=com.elseplus.tun2socks\&hl=en\&gl=US) on your Android device.
  </Step>

  <Step>
    Open the app and fill in the following fields:

    * **Socks host** (e.g., `gate.decodo.com`).
    * **Port** (e.g., `7000`).
  </Step>

  <Step>
    Set up the authentication:

    * **Username**: Proxy username (e.g., `user-proxyusername-session-1-sessionduration-60-country-us`).
    * **Password**: Proxy password.

    <Warning>
      - Ensure you are using **advanced parameters** directly in the proxy username to specify the **location** and keep the IP from **rotating** with residential and mobile proxies.
      - Refer to the [**Common Issues**](https://help.decodo.com/docs/tun2socks-integration?isFramePreview=true#socks5) section below to learn how.
    </Warning>
  </Step>

    Tap **START CONNECT** to activate the proxies.

### Verify the Connection

* Open a browser and visit [**ip.decodo.com**](https://ip.decodo.com/). If successful, your IP address will display the location of the proxy.

## Common Issues

### Blocklist

⚠️ Please be aware that we [**restrict access to some websites**](https://decodo.com/faq/general/do-you-have-any-blocked-sites).

### `SOCKS5`

**Residential and Mobile Proxy Support Limitations**

<AccordionGroup>
  <Accordion title="Country Targeting" icon="gear">
    The `gate.decodo.com` **endpoint** and the `7000` **port** must be used to utilize `SOCKS5` Residential or Mobile proxies. **Country** endpoints, such as `us.decodo.com`, will not function!

    You can target specific locations instead by specifying the location in your username using **advanced** **parameters**:

    * e.g.: `user-username-country-us` will connect to the **USA** pool.
  </Accordion>

  <Accordion title="Proxy Rotation" icon="gear">
    To get a **sticky** `SOCKS5` Residential or Mobile proxy in a **tool**, you must use a `session` **parameter**. Otherwise, the proxy will always rotate even with a set `sessionduration` parameter.

    * e.g.: `user-username-session-abc123-sessionduration-30` will connect to the same session.
      * The **session ID** name can be defined by any string of your choice.
  </Accordion>
</AccordionGroup>

<Note>
  Learn more in our **advanced** **parameter** guides for [**Residential**](https://help.decodo.com/docs/residential-proxy-advanced-parameters/) and [**Mobile**](https://help.decodo.com/docs/mobile-proxy-advanced-parameters/) proxies.
</Note>

### Direct IP

<AccordionGroup>
  <Accordion title="Direct IP Parameter Support" icon="gear">
    If you buy an IP list, you can specify which IPs to connect to using the **direct** `ip` parameter in the proxy username: `user-username-ip-x.x.x.x`

    * Supported products: **DC Pay/IP**, **Dedicated DC**, **ISP Pay/IP**, **Dedicated ISP** plans.
    * Products that offer access to the full proxy pool, such as residential proxies, do not support this parameter.
  </Accordion>

  <Accordion title="IP:PORT Format" icon="gear">
    * Decodo proxies don't support an `IP:PORT` format by default.
    * You must use the **endpoint** rotator format (e.g., `us.decodo.com:10101`).
    * If necessary, try the workaround [**here**](https://help.decodo.com/docs/how-to-get-ip-port-format#/), but it only works temporarily before requiring another setup update.
  </Accordion>
</AccordionGroup>
