Upstream Bind Settings

These settings affect how Pomerium will connect to an upstream service.

Source Address

By default, Pomerium relies on the OS to pick an appropriate network interface for outgoing connections to an upstream service.

To override the default, you can set a specific Source Address. All connections to upstream services will be bound to this address.
