I added these directives to the route-eth0:192 file:

ADDRESS0=192.168.6.9 NETMASK0=255.255.255.0 GATEWAY0=192.168.6.1

Which should have been:

ADDRESS0=192.168.6.0

NETMASK0=255.255.255.0 GATEWAY0=192.168.6.1

If you were to use ip route syntax, I believe you could set a Metric so you have a floating default route out the 192.168.6.0/24 network.

192.168.6.0/24 via 192.168.6.1 metric 10

There may be a way (though not mentioned in the docs below) to accomplish the same thing using network/netmask syntax you used in your example.

But it still doesn't matter. Your netmask in the ifcfg- file already covers that range and you don't need another route/GATEWAY for it. You don't need the route- file at all.

Agreed, no need for a route file. Just pull the gateway line from the ifcfg file for the internal network. ( I'm just posting the syntax/alternatives for anybody else's sake. )

Thank you. I was grasping at straws in this case to solve a strange routing problem that turned out to be a misconfigured gateway firewall. It was a very odd error because it only affected one of our off-site net-blocks. So tracking it down cause a little more hair-pulling than usual.

Fixed for now.
