Overview

In this guide, you can learn how to connect to MongoDB by using a SOCKS5 proxy. SOCKS5 is a standardized protocol for communicating with network services through a proxy server.

Tip

To learn more about the SOCKS5 protocol, see the Wikipedia entry on SOCKS.

SOCKS5 Proxy Settings

The proxy settings specify the SOCKS5 proxy server address and your authentication credentials. You can specify your settings in an instance of MongoClientSettings or in your connection string.

Important

The driver ignores the proxy settings if either of the following are true:

A Unix domain socket handles the communication. For more information, see the UnixServerAddress documentation.
TransportSettings are configured. For more information, see the TransportSettings documentation.

The following table describes the SOCKS5 client options:

Name	Accepted Values	Description
proxyHost	String	Specifies the SOCKS5 proxy IPv4 address, IPv6 address, or hostname. You must provide this value to connect to a SOCKS5 proxy.
proxyPort	non-negative Integer	Specifies the TCP port number of the SOCKS5 proxy server. This option defaults to `1080` when you set `proxyHost`.
proxyUsername	String	Specifies the username for authentication to the SOCKS5 proxy server. The driver ignores `null` and empty string values for this setting. The driver requires that you pass values for both `proxyUsername` and `proxyPassword` or that you omit both values.
proxyPassword	String	Specifies the password for authentication to the SOCKS5 proxy server. The driver ignores `null` and empty string values for this setting. The driver requires that you pass values for both `proxyUsername` and `proxyPassword` or that you omit both values.

Examples

The following examples show how to instantiate a MongoClient that connects to MongoDB by using a SOCKS5 proxy. The proxy settings can be specified in a MongoClientSettings instance or a connection string. These examples use the placeholder values described in the SOCKS5 Proxy Settings section. Replace the placeholders with your proxy settings.

Specify Proxy Settings in the MongoClientSettings

The following code example shows how to specify your SOCKS5 proxy settings by using the MongoClientSettings builder:

MongoClient mongoClient = MongoClients.create(
    MongoClientSettings.builder()
        .applyConnectionString(
                new ConnectionString("mongodb+srv://myDatabaseUser:myPassword@example.org/"))
        .applyToSocketSettings(builder ->
                builder.applyToProxySettings(proxyBuilder ->
                        proxyBuilder
                            .host("<proxyHost>")
                            .port(<proxyPort>)
                            .username("<proxyUsername>")
                            .password("<proxyPassword>")
                        )
        ).build());

Specify Proxy Settings in the Connection String

The following code example shows how to specify your SOCKS5 proxy settings in your connection string:

String connectionString = "mongodb+srv://myDatabaseUser:myPassword@example.org/" +
        "?proxyHost=<proxyHost>" +
        "&proxyPort=<proxyPort>" +
        "&proxyUsername=<proxyUsername>" +
        "&proxyPassword=<proxyPassword>";
MongoClient mongoClient = MongoClients.create(connectionString);
