add IP route using a single ip address? 1

[volleyman]

All,

I have a unique situation. I am in the middle of a implementing new firewalls and new internet connections. for a dmz, I have a cisco switch that is plugged into the dmz ports on the old and the new firewalls. As such, we have 2 paths to get to the same dmz.

right now, I want all traffic headed for the dmz to go through the old firewall, which is working...except for traffic heading to a single host. Is there a way to add a route for a single address rather than an entire network on our core router?

would this be a job for policy-based routing?

Can't remember the specific rules of overlapping routes, but It seems like you could just add a route for that one ip address. The router will match the most specific (longest subnet mask) for an IP. So could he just add a new static route like: ip route x.x.x.x 255.255.255.255 y.y.y.y

does that work? could it really be that simple? I just added the command and the router took it, so I'm testing some traceroutes now...gotta open ping since its on the dmz first though. results forthcoming.
