Hello , 
I want to know if I take 
ethernet1 10.0.0.1/24
wlan1 192.168.1.1/24

put them together in a bridge (and won't give the bridge address)
will both subnets will talk with out any firewall rules?

meaning - 
a computer with 10.0.0.2 and a computer on 192.168.1.5 will be at the same network?
assuming the gate way will be 10.0.0.1 and 192.168.1.1 ?

Thanks ,

What exactly are you trying to achieve?

to be able to talk with 2 networks without any firewall rules 

yes, and you don't need a bridge for it. As long as the router is the default gateway for each subnet.

If the two networks are on the same router, they will be reachable within the same router. 

you should add route for it

the route will be added automatically when you add the IP address. 
So, as soon as you add 10.0.0.1/24 as the address for ether1, a route will be added for 10.0.0.0/24.

To answer your question, no it will not work.

Do not bridge the two interfaces. Just ensure that there is a route between the two and you should be good.

What you're asking is like saying you plugged two different networks into a dumb hub or switch and expect them to communicate.
