# port-forward
Forward ports from a workspace to the local machine. Forward ports from a workspace to the local machine. For reverse port forwarding, use "coder ssh -R".
Aliases:
- tunnel
## Usage
```console
coder port-forward [flags] <workspace>
```
## Description
```console
- Port forward a single TCP port from 1234 in the workspace to port 5678 on
your local machine:
$ coder port-forward <workspace> --tcp 5678:1234
- Port forward a single UDP port from port 9000 to port 9000 on your local
machine:
$ coder port-forward <workspace> --udp 9000
- Port forward multiple TCP ports and a UDP port:
$ coder port-forward <workspace> --tcp 8080:8080 --tcp 9000:3000 --udp 5353:53
- Port forward multiple ports (TCP or UDP) in condensed syntax:
$ coder port-forward <workspace> --tcp 8080,9000:3000,9090-9092,10000-10002:10010-10012
- Port forward specifying the local address to bind to:
$ coder port-forward <workspace> --tcp 1.2.3.4:8080:8080
```
