Is your client connected under Opal or under the main router?

If it connected under Opal, you only need change any 192.168.0.0/24 to other. Then add 192.168.0.0/24 to S2S.
If it connected under main router, you need set route rule in you main router. such as you want access 192.168.0.23 in “Home” from “Office”, you need add route rule in office main router.
