Redirect /path to another subdomain

Hi everyone!
I am posting this because I have doubts on how to implement this and since I am not a super network expert I would like to have some advice.
Yesterday I exposed a vaultwarden container and everything works fine, to be clear it something like vault.mydomain.com. I noticed though that the admin page is still visible to everyone (of course a token is needed to access it). To limit access to it I thought of redirecting /admin to something like vault.intern.mydomain.com. Is something like this even possible? If you need details on how I configured traefik of course just ask.

Thanks to anyone

You can create an additional router with rule Host() && PathPrefix(`/admin`), then use redirect middleware and noop@internal service.

@bluepuma77 Thanks for the reply:

I tried with something like this:

labels:
      traefik.enable: true
      traefik.docker.network: proxy
      traefik.http.routers.vaultwarden.rule: Host(`pass.${DOMAIN}`)  && PathPrefix(`/admin`)
      traefik.http.routers.vaultwarden.entryPoints: https-external
      traefik.http.routers.vaultwarden.middlewares: redirect-to-404@file
      # Router for /admin path on pass.home.mydomain.com
      traefik.http.routers.vaultwarden-admin.rule: Host(`pass.home.${DOMAIN}`) && 
      PathPrefix(`/admin`)
      traefik.http.routers.vaultwarden-admin.entryPoints: https

with middlewares as:

redirect-to-404:
      errors:
         status:
            - "404"
         service: noop@internal

So my mind process was like this:
If user reaches pass.mydomain.com and tries to access path /admin it receives a 404
If the user reaches pass.home.mydomain.com then he can access /admin (which is an internally reachable only subdomain)
