For Apache 2.2 I use this module:
	http://www.openinfo.co.uk/apache/index.html

In mod_perl (1.x) the following should work:

httpd.conf:
   PerlPostReadRequestHandler ProxyIP

And then put something similar to the ProxyIP::handler function in  
your startup.pl:

    https://svn.develooper.com/combust/trunk/apache/conf/startup.pl

($config->proxyip_forwarders there returns a list of IPs, optionally  
with netmasks or '*' to just allow everyone).

The Perl version here traverses all the "trusted" upstream proxies  
and sets the IP to the first "untrusted" IP found - I forget if the  
Apache module does that too.
