# Tailscale VPN
|
|
|
|
|
|
|
|
|
|
The [Tailscale VPN](https://tailscale.com/) can be used to access PiKVM from the Internet
|
|
|
|
|
when using [port forwarding](port_forwarding.md) is not possible or does not seem secure enough.
|
|
|
|
|
Tailscale is a convenient and free (for private use) tool for organizing a small VPN network.
|
|
|
|
|
|
|
|
|
|
Basic Tailscale usage like whats shown below is provided as an example,
|
|
|
|
|
any other setting or functionality needs to be redirected to the [Tailscale support](https://tailscale.com/contact/support/).

## Configuring the PiKVM
|
|
|
|
|
|
|
|
|
|
1. Install the client, run `tailscaled` service and register it in the network:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
[root@pikvm ~]# rw
|
|
|
|
|
[root@pikvm ~]# pacman -Syu
|
|
|
|
|
[root@pikvm ~]# pacman -S tailscale-pikvm
|
|
|
|
|
[root@pikvm ~]# systemctl enable --now tailscaled
|
|
|
|
|
[root@pikvm ~]# tailscale up
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
2. Follow the link to authorize this installation.
|
|
|
|
|
|
|
|
|
|
3. After success, perform reboot to make sure that everything is working correctly:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
[root@pikvm ~]# reboot
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
4. Now you can try to view the IP address of Tailscale network interface:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
[root@pikvm ~]# ip addr show tailscale0
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If everything is successful, PiKVM will become a member of your VPN network.
|
|
|
|
|
|
|
|
|
|
!!! warning "Do not update Tailscale if you don't have access to PiKVM without VPN"
|
|
|
|
|
Unfortunately sometimes updating the Tailscale client can cause problems due breaking changes.
|
|
|
|
|
This is a reality that has to be taken into account.

## Troubleshooting
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
[root@pikvm ~]# rw
|
|
|
|
|
[root@pikvm ~]# pacman -Rscnd tailscale
|
|
|
|
|
[root@pikvm ~]# rm -rf /var/lib/tailscale /var/cache/tailscale
|
|
|
|
|
[root@pikvm ~]# reboot
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
