Port forwarding
If your ISP has provided you with an external IP address for the router, you can configure port forwarding to access PiKVM.
!!! warning
* **[Change passwords](first_steps.md#getting-access-to-pikvm) before opening access to PiKVM from the outside Internet.**
* It's also a good practice to use only HTTPS (port 443) with a valid certificate (like [Let's Encrypt](letsencrypt.md)).
* Additionally, you can use a custom external port number instead of 443, for example 14438 to avoid common port scanners.
- The Web UI runs on port
80and443. - VNC (if you use it) runs on port
5900.
If you don't have an external IP address, then we recommend trying Tailscale VPN.
