GATEWAY is a bash variable - so whoever sets it last wins.  I would 
recommend putting it in /etc/sysconfig/network .. I would also make sure 
that there are no files in /etc/sysconfig/networking or in 
/etc/sysconfig/networking/profiles/default .. these get read after the 
/etc/sysconfig/network-scripts files .. and as I mentioned before - 
whoever sets it last, wins.
