others here are correct cheap consumer routers rarley have the option to handle multiple ip's better routers do. It is built in ipfire ( my choice of routers) on a old computer with 2-4 network cards or in a vm also works and I think it is available in pfsence or opensence and DDWRT just add a alias IP and then port forward to the server you want it togo to.
