Forward client IP address

[Fredrik Nygren]

Hi,
I'm running Varnish 1.1.2 with Apache at the backend. When I follow  
Apaches access logs all incoming clients have the same IP-number, the  
IP-number of my Varnish server of course. How do I forward the IP- 
number of an incoming request from Varnish to Apaches access logs? Is  
it possible?

Regards
