Wireguard is a modern, secure VPN protocol that can be used to set up a virtual private network (VPN) on a FreeBSD jail. Here’s how you can install the Wireguard VPN client in a FreeBSD jail:
- First, create a new jail using the command “jail -c -n jail_name”
- Next, enter the jail using the command “jail -i jail_name”
- Once inside the jail, update the package repository using the command “pkg update”
- Next, install the Wireguard package using the command “pkg install wireguard-tools”
- Once the installation is complete, you can generate a new private key and a public key using the command “wg genkey | tee privatekey | wg pubkey > publickey”
- Next, create a new configuration file for the Wireguard VPN client. The default location for the configuration file is “/usr/local/etc/wireguard/wg0.conf”, but you can also specify a different location.
- Add the public key and private key to the configuration file, and also configure the IP addresses for the VPN client and the VPN server, and the ports to be used.
- Once you have finished editing the configuration file, you can start the Wireguard VPN client using the command “wg-quick up wg0”
- To check the status of the VPN connection, you can use the command “wg show”
It’s important to note that the Wireguard VPN client will only work within the jail, you will need to configure a Wireguard VPN server on another machine, or a VPS, and add the public key of the jail’s Wireguard VPN client to the server’s configuration file.
Additionally, you should configure the firewall rules on the jail to allow the VPN traffic to pass through, and also configure the routing table to route the traffic through the VPN.
You should also note that, jail is a lightweight operating system-level virtualization that allows multiple instances of a FreeBSD operating system to run on a single host. It helps to isolate the applications and services running inside the jail from the host system and other jails.
