File providers & udp server & traefik & k3s

the dashboard shows well

but the traffic does not go - it does not return from the service

firewalls are all ok

if you connect inside a local network, everything works

the server itself means ok

What did I forget ? or don 't I know ?

I made http - and everything works

  red.yaml: |-
    http:
      routers:
        red-router:
          entryPoints:
            - websecure

          rule: Host(domen.com)
      services:
        red-service:
          loadBalancer:
            servers:
            - url: http://192.168.88.3:1880

    **ports:**
**      vpn:**
**        port: 51820**
**        protocol: UDP**
    volumes:
      - name: config-file
        mountPath: file/
        type: configMap

added ports
but it didn't help

maybe who knows how to do it ?
