+# Configuring Port Forwarding
+
+There are two ways to forward ports:
+
+- The Coder CLI port-forward command
+- SSH
+
+## The Coder CLI and port-forward
+
+For example:
+
+```console
+coder port-forward mycoderworkspacename --tcp 8000:8000
+```
+
+For more examples, type `coder port-forward --help`
+
+## SSH
+
+Use the Coder CLI to first [configure SSH](../ides.md#ssh-configuration) on your
+local machine. Then run `ssh`. For example:
+
+```console
+ssh -L 8000:localhost:8000 coder.mycoderworkspacename 
+```
+
+## Accessing the forwarded port
+
+After completing either Port Forwarding method, open a web browser on your local
+machine to access the Coder workspace process.
+
+```console
+http://localhost:<yourforwardedport>
+```
