redirect all invalid urls to a specific component with angular2 rc4

Question

I'm writing an angular2 rc4 application with "@angular/router": "3.0.0-beta.2".

for now I have two routes, welcome and help, and I created another route that will rediret everything else to the welcome component.

this is my routes.ts file:

import { provideRouter, RouterConfig } from "@angular/router";
import {WelcomeComponent} from "./welcome.component";
import {HelpComponent} from "./help.component";

export const routes:RouterConfig = [
    { path: "",redirectTo: "welcome"},
    { path: "welcome", component: WelcomeComponent },
    { path: "help",component: HelpComponent}
];

export const APP_ROUTER_PROVIDERS = [
    provideRouter(routes)
];

my server is GoLang and I have it configured that all invalid urls will redirect to index.html

so now if I browse for example: localhost/weclome2, it does shows me the content welcome component, but the url on the browser still points to welcome2 instead of welcome and I also get the following error in javascript console:

what am I missing ?

thanks!

update

According to a google search I found some responses on older versions of angular2, so I tried to adopt them to the new version with the following code:

export const routes:RouterConfig = [
    { path: "",redirectTo:"welcome",pathMatch:"full"},
    { path: "welcome", component: WelcomeComponent },
    { path: "help",component: HelpComponent},
    { path: "*",redirectTo:"welcome"}
];

but the results are exactly the same.

The new router uses '**' as opposed to a single '*'

export const routes:RouterConfig = [
    { path: "",redirectTo:"welcome",pathMatch:"full"},
    { path: "welcome", component: WelcomeComponent },
    { path: "help",component: HelpComponent},
    { path: "**",redirectTo:"welcome"}
];
