You could put the pi on its own subnet. That way if it's hacked, the rest of the network is protected. Just make sure your router admin interface doesn't answer on that subnet.
This option is sometimes referred to as a 'DMZ' and may be supported by the router. Also look for VLAN options.
DMZ in essence means "forward ALL ports" to X. You should only DMZ a host that you know is very secure as its attack surface is significantly increased. If you need just one or two services open, best to not use DMZ
