We are using Traefik as a proxy for our Nomad cluster. Traefik is configured to read from Consul. Our Nomad jobs use service tags to configure Traefik.

Traefik Configuration

```auto
[serversTransport]
  insecureSkipVerify = true
[metrics]
    [metrics.prometheus]

[entryPoints]
//Seemingly irrelevant data
    [entryPoints.rd15]
    address = ":21115"
    [entryPoints.rd16]
    address = ":21116"
    [entryPoints.rd16udp]
    address = ":21116/udp"
    [entryPoints.rd17]
    address = ":21117"
    [entryPoints.rd18]
    address = ":21118"
    [entryPoints.rd19]
    address = ":21119"
    [entryPoints.rd20udp]
    address = ":21120/udp"
    [entryPoints.rd8000]
    address = ":8000"
    [entryPoints.mongodb]
    address = ":27017"
//Seemingly irrelevant data

# Enable Consul Catalog configuration backend.
[providers.consulCatalog]
  prefix = "traefik"
  exposedByDefault = false

  [providers.consulCatalog.endpoint]
    address = "192.168.7.210:8500"
    scheme = "http"

[providers.file]
  directory = "/traefik/providers/configs"
  watch = true

```

```

Consul Tags

```auto
rustdesk-hbbr1
traefik.enable=true
traefik.tcp.routers.rustdesk-hbbr17.rule=(Host(`rd.sewcorp.com`))
traefik.tcp.routers.rustdesk-hbbr17.rule=HostSNI(`*`)
traefik.tcp.routers.rustdesk-hbbr17.service=rustdesk-hbbr17-service
traefik.tcp.routers.rustdesk-hbbr17.entryPoints=rd17
traefik.tcp.services.rustdesk-hbbr17-service.loadbalancer.server.port=31871
traefik.tcp.routers.rustdesk-hbbr19.rule=(Host(`rd.sewcorp.com`))
traefik.tcp.routers.rustdesk-hbbr19.rule=HostSNI(`*`)
traefik.tcp.routers.rustdesk-hbbr19.service=rustdesk-hbbr19-service
traefik.tcp.routers.rustdesk-hbbr19.entryPoints=rd19
traefik.tcp.services.rustdesk-hbbr19-service.loadbalancer.server.port=26878
rustdesk-hbbs
traefik.udp.routers.rustdesk-hbbs-udp16.service=rustdesk-hbbs-udp16-service
traefik.udp.routers.rustdesk-hbbs-udp16.entryPoints=rd16udp
traefik.udp.services.rustdesk-hbbs-udp16-service.loadbalancer.server.port=28802

```

Traefik picks up the IP address without issue, but the port is always 0 for the `rustdesk-hbbs-udp16-service` service.

What am I missing?

The problem was related to a bug, the bug is now fixed [fix: UDP loadbalancer tags not being used with Consul Catalog by t3hchipmunk · Pull Request #9357 · traefik/traefik · GitHub](https://github.com/traefik/traefik/pull/9357)
