# Proxy Settings

> How to configure global inbound and outbound proxy settings in CData Arc.

The **Proxy Settings** portion of the **Security** page contains global inbound and outbound proxy settings. Connectors that support an outbound proxy (such as [AS3](https://docs.arc.cdata.com/26.4/self-hosted/en/connectors/as3.md)) default to these **Outgoing** settings, but you can configure individual connectors with separate proxy settings on the **Advanced** tab of some other connectors (for example, [FTP](https://docs.arc.cdata.com/26.4/self-hosted/en/connectors/ftp.md) and [SFTP](https://docs.arc.cdata.com/26.4/self-hosted/en/connectors/sftp.md)).
