I don't really understand your question, or your network setup.
Eth1 is simply providing the network 192.168.0.1/24, and connectivity for any devices connected to that subnet.If you plugged it into the same switch as from eth2/3/4, then it's not being used at all, given that your entire network seems to be running on 192.168.1.0/24.
The WAN_LOCAL rule allowing HTTP / HTTPS connectivity should be removed.
