[Dnsmasq-discuss] Subnetwork static route

I have a new question for everybody.

If I have a network: 192.168.0.x, and a subnetwork 192.168.1.x connected 
to it through a gateway with addresses: 192.168.0.4 and 192.168.1.1 on 
the two network devices.

To send traffic to the subnetwork from the network, I'd need a static 
route: something like:

dhcp-option:option:classless-static-route=192.168.1.0/24,192.168.0.4

but this would place the route

"192.168.1.0/24 via 192.168.0.4" in my gateway, sending the gateway's 
traffic to the wrong network device.


So do I use tags like this:

     dhcp-host=11:22:33:44:55:66,192.168.0.4,set:gw1

dhcp-option:tag:!gw1,option:classless-static-route=192.168.1.0/24,192.168.0.4

or do I move configuration of 192.168.0.4 out of dnsmasq:

     dhcp-host=11:22:33:44:55:66,ignore

dhcp-option:option:classless-static-route=192.168.1.0/24,192.168.0.4

and configure the gateway's network devices manually (in 
/etc/network/interfaces, etc.)?


I thought of maybe setting a higher metric for the inter-network static 
route, but I cannot find anywhere in dnsmasq or DHCP options where the 
metric can be set.


What is the common solution to this problem?
