I’m not really sure I’m following but you shouldn’t need Traefik to install n8n, you can use any other reverse proxy or just run n8n on its own.

Traefik, or any other reverse proxy, doesn’t affect anything with your router. You’d just need to update whatever you’re using for DNS to point to it.

You should still be able to access all your other services just fine unless you’re already running another reverse proxy with a wildcard DNS rewrite.
