How can I get client's real IP behind F5

Hi all,
I use F5 for load balance, and how can I get client’s Real IP, I had
tried the NginxHttpRealIpModule, but it doesn’t work.
And my log format: $remote_addr - $remote_user [$time_local] “$request”

'$status $body_bytes_sent “$http_referer” ’
'"$http_user_agent" ’

You should configure adding “X-Forwarded-For” header on F5 and
set “real_ip_header X-Forwarded-For”;
