# Sharing TCP Ports ::pro
|
|
|
|
Expose not only allows you to share your local development URLs, but you can also use Expose to share any of your local TCP ports.
|
|
|
|
For example, you might want to share your local copy of [HELO](https://usehelo.com) so that your PHP application can send test emails right through your local SMTP server.
|
|
|
|
You can share a local TCP port by calling `share-port` followed by the local port number that you want to share:
|
|
|
|
```bash
|
|
expose share-port 2525
|
|
```
|
|
|
|
The Expose server will assign a random TCP port that you can then use on other servers and services to connect to the tunnel. |
