I'm not sure what will work exactly for you, but here's a few things you can try to approach this (read carefully because nginx is confusing):

  1. Define service for your deployment, and make sure it covers port routes you want and support on deployment end:

     apiVersion: v1
 kind: Service
 metadata:
   name: web-app
   namespace: web
   labels:
     app: web-app
 spec:
   ports:
   - port: 80
     targetPort: 1337
     protocol: TCP
   selector:
     app: web-app

  2. Refer to it in nginx ingress:

     rules:
 - host: mycoolwebapp.com
   http:
     paths:
     - path: /
       pathType: Prefix
       backend:
         service:
           name: web-app
           port:
             number: 80

The catch here is that you can route ALL services via port 80 but use any target port you want, so that you can, say, add 50 ingress hosts/routes over a morning routing to port 80 and only difference they'll have is target port in service.
3. If you are specifically unhappy with ports 80 and 443, you are welcome to edit ingress-nginx-controller (service one, because as I said nginx is confusing).
4. Alternatively, you can find example of ingress-nginx-controller service on the web, customize it and apply, then connect ingress to it... but I advise against this because if nginx doesn't like anything you set up as custom service, it's easier to just reinstall whole helm release of it and try again.
