SSH Remotely to Server Running Wireguard VPN Client Connection
This article covers the process of securely connecting to a remote server that has an OpenVPN server and Wireguard VPN client running. Specifically, we will discuss how to create a virtual interface IP address, forward appropriate ports, and establish a stable SSH connection.
Prerequisites
- A server with an OpenVPN server and Wireguard VPN client installed.
- SSH access to the server.
Creating a Virtual Interface IP Address
The first step is to create a virtual interface IP address on the server. This will allow us to route traffic through the Wireguard VPN client. To do this, we will use the following command:
sudo ip addr add /24 dev wg0 Replace
sudo ip addr add 10.0.0.1/24 dev wg0Forwarding Appropriate Ports
Once the virtual interface IP address has been created, we need to forward the appropriate ports. This will allow us to establish a stable SSH connection to the server. We will need to forward both the OpenVPN server port and the Wireguard VPN client port.
To forward the OpenVPN server port, we will use the following command:
sudo iptables -t nat -A PREROUTING -p udp --dport -j DNAT --to-destination Replace
To forward the Wireguard VPN client port, we will use the following command:
sudo iptables -t nat -A PREROUTING -p udp --dport -j DNAT --to-destination Replace
Establishing a Stable SSH Connection
Now that we have created a virtual interface IP address and forwarded the appropriate ports, we can establish a stable SSH connection to the server. To do this, we will use the following command:
ssh @ Replace
- Create a virtual interface IP address on the server using the
ip addr addcommand. - Forward the OpenVPN server port and Wireguard VPN client port using the
iptablescommand. - Establish a stable SSH connection using the
sshcommand and the virtual interface IP address.
