Which OS are you using?  The FC3 network intialization stanza looks 
like:

# Add non interface-specific static-routes.
if [ -f /etc/sysconfig/static-routes ]; then

  grep "^any" /etc/sysconfig/static-routes | while read ignore 
args ; do
 
 /sbin/route add -$args

done
fi 

which searches for any line beginning with the word "any".  Anyway, 
try it without the "-" on "-net". For example:

# route -n

0.0.0.0      192.168.1.6  0.0.0.0         UG 0  0  0 eth0

# vi static-routes
# cat static-routes
