IP_FORWARD /etc/sysconfig/network magic words?

[Jeff Kinz]

In the file /etc/sysconfig/network, does the line :

FORWARD_IPV4=YES

actually control IP forwarding?  Currently my system seems to be
ignoring it.  ie - I font actually get any ip-forwarding happening when
the network is up unless I explicitly enable it.

I know that:
echo "1" > /proc/sys/net/ipv4/ip_forward

will turn it on and 

echo "0" > /proc/sys/net/ipv4/ip_forward

will turn it off.   Is there any option I can set in
/etc/sysconfig/network or in any ofthe file under /etc/sysconfig
that will automatically start IP forwarding whenever the network
services are on?
