iplanet v6 : how to record original client ip when login.

Magnus.conf iPlanet Default Flex Log Format:

Init fn="flex-init" access="$accesslog" format.access=%Ses->client.ip% - %Req-
>vars.auth-user% [%SYSDATE%] '%Req->reqpb.clf-request%' %Req->srvhdrs.clf-
status% %Req->srvhdrs.content-length%

Change it to:

fn="flex-init" access="$accesslog" format.access=%Req->headers.x-forwarded-
for% - %Req->vars.auth-user% [%SYSDATE%] '%Req->reqpb.clf-request%' %Req-
>srvhdrs.clf-status% %Req->srvhdrs.content-length%
