Steering subnet traffic in OSPF

Internal network uses OSPF to include inside interface of ASA 5585X firewall.

The ASA has a static route 0.0.0.0 /0 pointing to the edge router which is also redistributed into OSPF.

The edge router has a static route 192.168.0.0 /22 pointing to the ASA.

A new firewall has been installed in the network with it's inside interface participating in OSPF.

On the edge router a more specific route, 192.168.X.0 /24, can be added that points to the new firewall.

On the new firewall a static route 0.0.0.0 /0 can be added that points to the edge router and NOT redistributed into OSPF.

Question: How best to steer particular 192.168.X.0 /24 subnet traffic out through the new firewall to the Internet?
