forwarding original IP address

Hi everyone

This is probably very easy but I thought I'd check I've got this right first.

On my web server, I want to display the original IP address of the client, not the IP of the varnish server, in the error logs from the web server.

I've done some reading and found this example in the docs

sub vcl_recv {

# Add a unique header containing the client address

	remove req.http.X-Forwarded-For;
	set    req.http.X-Forwarded-For = req.http.rlnclientipaddr;

Is that all I need to do?

Any help, greatly appreciated.
