[lug] Linux Router Experimenting...Where is Metric Set?

So I'm experimenting with using Linux for a router instead of buying something off the shelf. Something I ran into that I'm not quite sure of where to "fix" is the route metric. On this same private network hosts I created statically have a metric of "0" for the 192.168.x.x subnet, while those picking up the same information via DHCP have a metric of "1". This is causing forwarding to fail unless I manually set metric back to "0", which kind of defeats the purpose of DHCP automation. Here's an example:
# routeKernel IP routing tableDestination     Gateway         Genmask         Flags Metric Ref    Use Ifacedefault         myrouter         UG    0      0        0 eth0192.168.2.0     *        U     1      0        0 eth0 
My question is whether the DHCP server should be sending something to get this metric to be 0, or if the dhcp client should be configured to do this...or if perhaps technically speaking this should be automatic and never messed with? Perhaps it is a case of needing "default" to instead use a metric of "1" to match subnet metric?
