[CentOS] ip_forwarding

Hey all,

I'm trying to swap to CentOS and I have just about everything working
except ip_forwarding.

I have
FORWARD_IPV4="yes"
in my /etc/sysconfig/network file but /proc/sys/net/ipv4/ip_forward does
not = 1 (also tried to set it to ="true" and just =true).

All the firewall (iptable) rules are in place.  Why won't ip_forward stay
enabled?

I'm using the latest DL of CentOS and all updated.  Any ideas?

Cheers.
