Some organizations require that you use a proxy server to access servers outside the organization’s local network.

FTP Proxies

Transmit supports 10 common types of basic FTP proxy server authentication, as well as SOCKS 4, 4a, and 5.

To use a proxy server:

1. Choose Transmit > Settings
2. Click Advanced
3. Choose a proxy server type from the popup. A description of the proxy authentication process that you’ve chosen appears below the popup.
4. Enter the proxy server address, port, user name, and password (as required) in the fields provided.

SFTP Proxies

Support for SFTP proxies was introduced in Transmit 5.1. When using key based authentication, Transmit does not require any additional configuration.

If your proxy server requires password based authentication, you’ll need to add the password to Transmit’s Settings using the following steps:

1. Choose Transmit > Settings
2. Click Advanced
3. Enter your proxy password into the SFTP Proxy Password field
4. Close the preferences to save your changes

HTTP Proxies

Transmit 5 will utilize http proxies specified in the macOS network settings. Information on configuring these settings in System Settings can be found on Apple’s Suport Site.
