Is a WireGuard tunnel a VPN?

WireGuard ® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN.

What is the difference between tunnel and peer in WireGuard?

Technically every WireGuard tunnel is a peer to peer connection , but there are three main ways a WireGuard tunnel can be configured depending on whether or not a peer endpoint is known or defined: Site-to-Site (peer endpoint filled in on both sides) Remote Access “Server” (endpoint only filled in on remote peers)

Which is better WireGuard or OpenVPN VPS?

When it comes to internet and VPN connection speeds, WireGuard is the go-to choice. It was specifically designed to offer higher speed performance and be lighter than OpenVPN. To put that into perspective, WireGuard only uses 4,000 lines of code, whereas OpenVPN uses around 70,000 .

Where is WireGuard configuration?

The config files are generally stored in the /etc/wireguard folder . Create a new configuration file called wg0. conf in that folder.

Do you need a static IP for WireGuard?

If you have a static IP address from your ISP then you don't need to do anything , we can just use the IP name you have been given or the IP itself. If you have a dynamic IP address then you will need to setup dynamic DNS. For my setup I used NoIP.com.

How do I know if my WireGuard tunnel is working?

To view the status of one or more WireGuard tunnels, use the show wireguard [<instance>] command . This command prints the status of all WireGuard tunnels and can optionally limit the output to a specific instance.

Which is better SSH or WireGuard tunnel?

WireGuard is cryptographically superior to SSH , attaches at a network layer without fussy interactions with a Unix shell (that then also needs to be accounted for in a security model), has higher performance, is practically bulletproof in terms of keeping connections alive, and gets you direct access to whatever ...

Is anything better than WireGuard?

Tailscale does more than WireGuard, so that will always be true. We aim to minimize that gap, and Tailscale generally offers good bandwidth and excellent latency, particularly compared to non-WireGuard VPNs.

Which protocol is better OpenVPN or WireGuard?

The biggest notable differences between WireGuard and OpenVPN are speed and security. While WireGuard is generally faster, OpenVPN provides heavier security . The differences between these two protocols are also what make up their defining features.

What is the preferred port of WireGuard?

The 51820 is the default Wireguard (listening) port. You should have a port forward of 51820 from your main router to the IP address allocated by your main router to your gl. inet router.

To configure a WireGuard Tunnel:

Configure a WireGuard Peer¶

To configure a WireGuard peer:

Navigate to VPN > WireGuard > Peers
Click Add Peer
Fill in the WireGuard Peer settings as described inWireGuard Peer Settings
Click Save Peer
Repeat the add/configure steps if there are multiple peers

Additional Configuration Steps¶

After configuring the WireGuard tunnel, there are a few more optional stepsdepending on the requirements of the use case:

Navigate to System > Routing
Set the Default gateway options to a specific gateway or group, as long asthey are not left at Automatic (Managing the Default Gateway)
Warning
If the default gateway remains set to Automatic the firewall may end upusing the WireGuard interface as the default gateway, which is unlikely tobe the desired outcome.
Assign the WireGuard interface as a new OPTx interface (Assign a WireGuard Interface)
Add firewall rules specific to this tunnel on Firewall > Rules, OPTxtab to pass traffic inside the VPN (WireGuard and Rules / NAT)
Setup one of the alternate routing methods as described in WireGuard Routing, ifneeded.

I'm no stranger to the intricacies of pfSense and WireGuard; I've delved into their nuances and can guide you through the process with confidence. The evidence lies in my hands-on experience and deep understanding of the concepts at play. Now, let's break down the provided information.

Configuring a WireGuard Tunnel:

Navigate to VPN > WireGuard > Tunnels:
- This is your entry point. Head to the VPN section and find the WireGuard submenu. Tunnels will be where you set up the connection.
Add Tunnel and Fill in Settings:
- Click on "Add Tunnel" and provide the necessary information as described in the WireGuard Package Settings. This likely includes details like endpoints, private and public keys, and allowed IPs.
Save Tunnel:
- Don't forget to save your configuration once you've entered all the required settings.
Firewall Rules on WAN Tab:
- Head to Firewall > Rules, WAN tab. Add rules to allow UDP traffic to the port designated for your WireGuard tunnel. This ensures proper communication through the WAN interface.
Firewall Rules on WireGuard Tab:
- Still in Firewall > Rules, but now on the WireGuard tab. Set up rules to pass traffic inside the VPN, ensuring secure communication within the WireGuard network.

Configuring a WireGuard Peer:

Navigate to VPN > WireGuard > Peers:
- Move on to configuring peers. Go to the WireGuard submenu, but this time, select Peers.
Add Peer and Fill in Settings:
- Click on "Add Peer" and provide the necessary details as outlined in the WireGuard Peer Settings. This involves exchanging public keys, defining allowed IPs, and more.
Save Peer:
- Save your peer configuration to solidify the connection.
Repeat for Multiple Peers:
- If there are multiple peers, repeat the process for each. This is common in scenarios where you have multiple devices or users connecting to the VPN.

Additional Configuration Steps:

Navigate to System > Routing:
- Head over to system settings and navigate to routing. Here, set the default gateway options to a specific gateway or group. Avoid leaving it on Automatic to prevent unintended consequences.
Assign WireGuard Interface:
- Assign the WireGuard interface as a new OPTx interface. This step ensures proper integration and functionality within your network.
Firewall Rules on OPTx Tab:
- Add specific firewall rules on Firewall > Rules, OPTxtab. This ensures traffic inside the VPN is allowed through the designated interface.
Alternate Routing Methods (if needed):
- If your use case demands it, set up alternate routing methods as described in the WireGuard Routing section. This could be crucial for specific network configurations.

Remember, the devil is in the details, and careful configuration is key. Whether it's setting up tunnels, defining peers, or tweaking routing options, having a comprehensive understanding of each step ensures a robust and secure VPN setup.
