Using the same Istio GateWay with multiple ports and protocols

I am trying to configure an istio GateWay with two different protocols (GRPC and HTTP)

Right now, I have two different gateways one each for GRPC and HTTP as below

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwgrpc
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7878
      name: http
      protocol: GRPC
    hosts:
    - "*"
---
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwrest
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7979
      name: http
      protocol: HTTP
    hosts:
    - "*"

Is it possible to use same gateway with different protocols and ports?

You should be able to combine the two Gateways. The only problem is that both your ports have the same name. Something like this should work.

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwgrpc
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7878
      name: grpc
      protocol: GRPC
    hosts:
    - "*"
  - port:
      number: 7979
      name: http
      protocol: HTTP
    hosts:
    - "*"

You may want use this example as a template. Agree with @Frank: You need to change the name. Here is a small part of an example config

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: my-gateway
spec:
  selector:
    app: my-gatweway-controller
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - uk.bookinfo.com
    - eu.bookinfo.com
    tls:
      httpsRedirect: true # sends 301 redirect for http requests
  - port:
      number: 443
      name: https
      protocol: HTTPS
    hosts:
    - uk.bookinfo.com
    - eu.bookinfo.com
