Function guard_remote_exposure 

pub fn guard_remote_exposure(
    remote_bind: &str,
    accepted: bool,
) -> Result<(), SshCliError>

Rejects a reverse forward that would publish a remote listener.

The mirror of guard_network_exposure for the inverted direction. The address is not parsed as an IP because RFC 4254 also assigns meaning to names and to the empty string (all interfaces), so an IP parser would reject the very forms that matter most.

Errors

SshCliError::InvalidArgument (exit 64) when the remote bind is routable and accepted is false.
