Is it possible to access a different service with a port from the same hostname?

Hi,

• Gateway-API NLB Listeners Port 80, 800, 8888

• Gateway-API Manifest Port

spec:
  gatewayClassName: istio
  listeners:
    - allowedRoutes:
        namespaces:
          from: All
      hostname: '*.foobar'
      name: http
      port: 80
      protocol: HTTP

    - allowedRoutes:
        namespaces:
          from: All
      hostname: '*.foobar'
      name: foobar-b
      port: 800
      protocol: HTTP

    - allowedRoutes:
        namespaces:
          from: All
      hostname: '*.foobar'
      name: foobar-c
      port: 8888
      protocol: HTTP

- httpRoute
{...}
hostnames:
- test.frist.second.foobar
{...}
service:
  type: ClusterIP
  ports:
    - port: 80
      protocol: TCP
      name: foobar-a
      targetPort: 8000
    - port: 800
      protocol: TCP
      name: foobar-b
      targetPort: 800
    - port: 8888
      protocol: TCP
      name: foobar-c
      targetPort: 8888

• test.frist.second.foobar/foobar 접속 => Connect traffic to 80 service

• test.frist.second.foobar:800/foobar 접속 => Connect traffic to 800 service

• test.frist.second.foobar:8888/foobar 접속 => Connect traffic to 8888 service

Even if I call it by specifying the listeners Port in hostname 'test.frist.second.foobar', it is connected to the same 80 service. Is it possible to access a different service with a port from the same hostname?

That should be possible. Hard to say if you did something wrong or not since you didn't include the routes.
