Proxifier

Proxyfier Proxy Setup Guide

Proxifier is a network utility for Windows and macOS that enables applications to connect through SOCKS5 and HTTPS proxies. It tunnels traffic to bypass firewalls, enhances privacy by masking your IP address, and provides granular control over network connections.

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).

SOCKS5

🚧

Residential and Mobile Proxy Support

  • SOCKS5 for residential and mobile proxies requires specific settings to target the correct locations and prevent proxy rotation:
Country Endpoint Support

Please note that you must use the gate.decodo.com endpoint and the 7000 port 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.
Proxy Rotation

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.

Direct IP

Direct IP Parameter Support

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.
IP:PORT
  • 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, but it only works temporarily before requiring another setup update.
