Routing issue

I have sophos home with three network connections.

Interface 1 is a 10.0 /8

Interface 2 is a 172.16 /16

Interface 3 is the WAN (192.16) connected to a FIOS router.

I can get out to the internet on both the 10.0 and 172 networks. They just don't talk to each other.

I've setup a policy of LAN to LAN with the 10 interface and the 172 interface.

I also setup objects for 10 and 172 and added a policy for that as well.

I tried adding unicast routes for each network pointing to the interfaces, even though I think this is not needed?

Thanks
