# Protocols

NetNut proxies support HTTP/HTTPS/ SOCKS5 protocols:

 **HTTP**

The code examples in the documentation use the HTTP protocol, which is supported by most libraries and third-party software.

<mark style="color:blue;">`curl`</mark>` ``-x USERNAME-res-any:PASSWORD@gw.netnut.net:9595 "example.site.com"`

**HTTPS / SOCKS5**

For added security with a fully encrypted connection, you can use the HTTPS / SOCKS5 protocols by adding socks5h:// to the proxy gateway, for example:

<mark style="color:blue;">`curl`</mark>` ``-x USERNAME-res-any:PASSWORD@socks5h://gw.netnut.net:9595 "https://example.site.com"`

Note: Some libraries and third-party tools may not support the HTTPS protocol.

Note: Some websites may identify a proxy IP when using the SOCKS5 protocol.

**UDP**

The UDP protocol is supported via our SOCKS5 gateway.&#x20;

This is ideal for applications requiring low-latency data transfers, such as VoIP, live streaming, or gaming, which are not compatible with standard HTTP proxies.

**How to use:**\
The configuration is similar to standard proxy usage. \
Use your proxy credentials with the UDP gateway endpoint:

`USERNAME-`**`udp`**`-any:PASSWORD@gw-udp.netnut.net:9595 "example.site.com"`

Ensure your application is configured to connect via **SOCKS5 with UDP support, and use the matching port (9595)**.

&#x20;Note: Standard HTTP proxies do not support UDP traffic. You must ensure your library or tool is configured to use SOCKS5 with UDP Associate support.

Note: While SOCKS5 enables UDP, some network environments or firewalls may still block UDP packets even when using a proxy.

**Default proxy ports**

| Port | Protocol |
| ---- | -------- |
| 80   | HTTP     |
| 443  | HTTPS    |
| 9595 | SOCKS5   |
