Noob Question

Illz
Hello,
I'm trying to get two network devices to at least ping one another on a different subnet.
I have 2 devices

Device 1
IP: 192.168.7.15
MASK: 255.255.255.0
GW: 192.168.7.1

Basic GB switch

Device 2
IP: 192.168.8.25
MASK: 255.255.255.0
GW: 192.168.7.1

Sophos Home UTM 9.

I know they should not be able to communicate through my layer -2 switch but if i assign the same GW which is a layer -3 device shouldn't they communicate?
 
What am i doing wrong? Or what am I not understanding?[:S]
Thank you

    Hey,  you can't assign the same gateway as the .8 network can't contact the .7 so it won't reach the gateway.      

    You will have to set the .8  gateway as whatever IP of the router on that range is, then create static routes between the networks.    

    You will also have to create firewall rules to allow certain traffic between the networks.
