How to use proxies with Proxifier

Proxifier forces traffic from applications that have no proxy setting of their own through a proxy at the system level, using rules that decide which programs are routed and which connect directly.

Recommended for Proxifier

ISP proxies — System-level routing usually serves desktop software that expects a stable connection rather than a rotating one.

Setup

1
Add the proxy server
Open Profile then Proxy Servers, add a server and enter host, port, protocol and credentials. Replace PROXY_HOST, PROXY_PORT, USERNAME and PASSWORD with the endpoint and credentials shown in your seamless dashboard.
2
Create a routing rule
Under Proxification Rules, add a rule naming the applications to route and pointing their action at the proxy you added. Leave the default rule as Direct so everything else is unaffected.
3
Resolve DNS through the proxy
Enable 'Resolve hostnames through proxy' in Name Resolution. Without it, your local resolver still sees every hostname the application looks up, which leaks the destinations you were trying to hide.
4
Confirm in the connection log
Proxifier's live log shows each connection and the route it took. Check that the application you targeted is going through the proxy and not straight out.

Proxifier proxy FAQ

What is Proxifier used for?

It routes traffic from applications that have no built-in proxy configuration through a proxy, by intercepting connections at the system level and applying per-application rules.

Does Proxifier support SOCKS5 with authentication?

Yes. SOCKS4, SOCKS5 and HTTPS proxies are supported, with username and password authentication for each.

Why is my application still showing my real IP?

Either no rule matches that application, or its hostnames are being resolved locally. Check the rule ordering, since the first match wins, and enable hostname resolution through the proxy.
