Can I set up the router in a way that the hosts can access the server at the bottom right? My preferred solution would be that when the hosts access 192.168.0.33 they are forwarded to 192.168.0.1 on the ether5 interface.
I don’t want to change the prefix of the hosts subnet. I could remove 192.168.0.1 from the bridge0 interface but if there’s a solution without doing that, it would be better.
Having same nerwork addresses on different interfaces always means problems. And case when connected device has same IP address as router itself (even though on unrelatted interface) borders to impossible. Fixing your setup by changing some network address is much easier than working around it. Which one to change (server off ether5 or network off bridge) is up to you (whichever is easier or possible).
