NekoBox on Windows adds a node through Manual Input. Set the type to Socks (version 5) or HTTP, type the gateway host in address and the port in port, fill the username and password in the authentication section and click OK. Start the node and switch on the system proxy to route Windows.
Main window → right-click the server list → Manual Input
Launch NekoBox, right-click an empty area of the server list and choose Manual Input from the menu.

In the Edit dialog set Type to Socks and Version to 5 for the SOCKS5 port, or Type to HTTP for the HTTP port. Type the gateway host in Address and the port in Port, then the username and password in the authentication fields. Click OK.

The node appears in the server list with its type, address and name.

Select the node and click the start button, then tick System Proxy in the toolbar (Tun mode for apps that ignore it). Open the QuantumProxies IP checker in a browser to confirm the exit IP.

The URL test on the node row, then the IP checker in a browser after System Proxy is on.
Routing rules in NekoBox can send only chosen apps or domains through the node; by default everything uses it once the system proxy is on.
Copy the line from the dashboard (Proxies, your plan, the proxy generator) rather than typing it: it already carries the country, the session id and the session length in the username. The table shows what each field holds.
| Plan | Host | HTTP port | SOCKS5 port | Username shape |
|---|---|---|---|---|
| Residential Premium | residentialpremium.quantumproxies.io | 8080 | 1080 | USER-country-us-sid-k3f9a1b2-ttl-60m |
| Residential Basic | residentialboson.quantumproxies.io | 9000 | from the generator | USER-country-us |
| Mobile | mobile-us.quantumproxies.io (also -eu, -as, ww) | 8080 | 1080 | USER-country-us-type-mobile |
| Datacenter (per GB) | datacenterboson.quantumproxies.io | 9999 | 10000 | USER-type-datacenter-country-de |
| IPv6 | ipv6.quantumproxies.io | 1001 | from the generator | USER-country-us-package-ipv6 |
| ISP (dedicated IP) | the IP of your line | 8000 | on the plan page | the line's own login |
The password is the one the generator prints next to the username. Pick HTTP or SOCKS5 in the tool and use the port of that column; a port from the other column is the most common reason a check fails. USER and the session id are placeholders for your own values.
Socks with Version 5 and the SOCKS5 port, or HTTP with the HTTP port. The address and login are the same for both.
The type and port probably disagree, or the username and password are empty: NekoBox marks them optional, our gateways need them.
NekoBox is the current name of the NekoRay project on Windows. The Android app with the same name has its own guide on this site.
