### Port range mapping
*Added in v0.56.0*
We can use the range syntax of Go template combined with the built-in `parseNumberRangePair` function to achieve port range mapping.
The following example, when run, will create 8 proxies named `test-6000, test-6001 ... test-6007`, each mapping the remote port to the local port.
```
{{- range $_, $v := parseNumberRangePair "6000-6006,6007" "6000-6006,6007" }}
[[proxies]]
name = "tcp-{{ $v.First }}"
type = "tcp"
localPort = {{ $v.First }}
remotePort = {{ $v.Second }}
{{- end }}
```
### Client Plugins
frpc only forwards requests to local TCP or UDP ports by default.
