Controls whether the indirect client address
	(see follow_x_forwarded_for) is used instead of the
	direct client address when spoofing the outgoing client.

	This has no effect on requests arriving in non-tproxy
	mode ports.

	SECURITY WARNING: Usage of this option is dangerous
	and should not be used trivially. Correct configuration
	of follow_x_forewarded_for with a limited set of trusted
	sources is required to prevent abuse of your proxy.
