WireGuard is a simple, fast and modern VPN. It aims to be faster and simpler than IPSec. It intends to be considerably more performant than OpenVPN. Initially released for the Linux kernel, it is now cross-platform and widely deployable. It is currently under heavy development. We will describe here how to set up WireGuard as a central server or just as a client. The setup of a central VPN server is very simple. Just go to tab Local and create a new instance.

Give it a Name and set a desired Listen Port. If you have more than one service instance be aware that you can use the Listen Port only once.

Peers can not be chosen yet since we have not created them yet.

After hitting Save changes you can reopen the newly created instance, write down your new public key and give it to the other side in a secure way e. Endpoint Address and Endpoint Port can be left empty since they are mostly dynamic, now hit Save changes.

Go back to tab Localopen the instance and choose the newly created endpoint in Peers. If you want to add more users just add them in Endpoints and link them via Peers. You also have a new interface Wireguard in rules, where you can set granular rules on connections inside your tunnel.

With this setup your clients can reach your internal networks when they add it via Allowed IPs. But what if you want to push all traffic via VPN in order to filter some streams out of it?

Check that rule generation is set to manual or hybrid. Add a rule and select your WAN as Interface. Now when you add 0. When assigning interfaces we can also add gateways to them.

This would offer you the chance to balance traffic via different VPN providers or do more complex routing scenarios. Choose your WireGuard interface and set the Gateway to dynamic.

If we have OPNsense also at the client side the configuration is similar to step 3a but you have to choose Allowed IPs within the range of the server side and exchange public keys after the creation of a new instance.

Then networks which should be routed via WireGuard have to be added to your Allowed IPs in the endpoint configuration of your client e. For pushing all network traffic via VPN you can add 0. Your tunnel is now up and running.Just looking on how to invoke the installer?

When the live environment has been started just login with user installer and password opnsense. Since version Embedded images nanobsd store logging and cache data in memory only, while full versions will keep the data stored on the local drive. A full version can mimic the behavior of an embedded version by enabling RAM disks, this is especially useful for SD memory card installations.

See the chapter Hardware Setup for further information on hardware requirements prior to an install.

The OPNsense distribution can be downloaded from one of our mirrors. Go to the OPNSense download page.

Remove the file name after the last slash in the URL bar, and press enter. This will take you to the directory listing for that mirror. The OpenSSL public key is required to verify against.

This file is also on the mirror directory listing page, however you should not trust the copy there. Download it, open it up, and verify that the public key matches the one from other sources. If it does not, the mirror may have been hacked, or you may be the victim of a man-in-the-middle attack.

Some other sources to get the public key from include:. Note that only release announcements with images typically all major releases contain the public key. Once you have downloaded all the required files and a copy of the public key, and verified that the public key matches the public key from the alternate sources listed above, you can be relatively certain that the key has not been tampered with. To verify the downloaded image, run the following commands substituting the names in brackets for the files you downloaded :.

If it has any other output, you may have made an error using the commands, or the image may have been compromised. USB installer image with live system capabilities running in serial console mode with secondary VGA support no kernel messages though.

Flash memory cards will only tolerate a limited number of writes and re-writes. Consider to enable an external syslog server as well.

Setting up WireGuard on OPNSense & Android

Please be aware that the latest installation media does not always correspond with the latest released version. OPNsense installation images are provided on a regular basis together with major versions in January and July. In order to apply your choice an update must be performed after save, which can include a reboot of the system. Download the installation image from one of the mirrors listed on the OPNsense website.

The easiest method of installation is the USB-memstick installer. The following examples apply to both. If you need to know more about using the serial interface, consult the serial access how-to.

The boot process gives you the opportunity to run several optional configuration steps.WireGuard has been causing quite a stir in networking over the last year or so, promising an easier way to manage VPN connections, and has some interesting benefits from my point of view. Note: All keys used shown in the screenshots are no longer in use and were created solely for the purposes of this post, no need to warn me, or try them out, I guarantee they've been nuked from orbit.

Firstly, it doesn't drain my battery like OpenVPN on my phone, opening up the possibility to leave it connected for much longer periods. Thirdly I often have to connect to a public WiFi access point at work, yeah, yeah, I know, it's difficult to believe in this day and age that I don't have access to a staff designated WiFi network, but it is what it is. I do however have occasion to use my laptop at work, and it would be useful to be able to access my LAN and my ever growing pool of services, and quite frankly, I don't want my traffic visible to all and sundry whilst I'm doing so, I previously used OpenVPN for this, but WireGuard is somewhat lighter on resources, so I decided to migrate.

For a long time I have been using PFsense, however, they don't seem to have any impending plans to implement WireGuard, and the interface of OPNsense is prettier to my eye, so being the sucker to eye candy that I am, and keen to try out WireGuard, I decided to migrate.

Long story short, it's not difficult to migrate, but you can't import your PFsense configuration directly into OPNsense, so I used a multistep approach. The advantage of this was there was little risk of me leaving the family without a working internet connection and incurring the wrath of the wife, and it actually worked out so well, I've kept both the virtualised PFsense instance and also created a backup OPNsense virtual machine, which can utilise a backup of my settings from the bare metal install should I ever need to do so.

I'm not going to discuss the relative merits of one vs the other, as it's an emotive issue, but I will say that I don't have any regrets on my decision to migrate. Here's a screenshot to feast your eyes on the beautiful UI. Click save, and you'll find that if you go back and edit the config, your private and public keys will have been generated for you. As the picture below shows. It should look like this, so click Save and you're good to go, just rinse and repeat for each client you want to add, just remembering to increment the Allowed IPs Tunnel each time, so the next client would be Now just go back to the Local tab and edit your config and select phone in the peers list.

As tempting as it may be to call it WireGuardthere is already an interface called that, which as I understand it from here is automatically created, and is a group for all the WireGuard tunnels you may create.

There are a couple of options to install WireGuard on your Android device, the two I know about are the official WireGuard application and Viscerion. For this tutorial I'm going to use the official application, although in practice, setting them up is identical. I'll leave it to your discretion on how you want to tackle this.

Once you've done that, you need to copy the OPNSense public key into the Peer setup on your phone, and the phone public key into the peer you created on your OPNsense install. I have seen other WireGuard implementations, such as the excellent one on the current release candidate of Unraid which generates all of the private and public keys for both devices on Unraid and provides a QR code to easily add them to your peers, whilst this is very straightforward, technically, neither device should ever "see" the other peer's private key.

Simply open the WireGuard app on your phone and click the toggle, you should find it connects, verify by looking at your OPNsense install. After submitting this article to my colleagues for their review, aptalca mentioned an interesting "hack". His very simple, but exceedingly clever method of circumventing this is by running WireGuard on port 53which is also UDP and therefore not able to be blocked.

I was genuinely impressed by this, and have to admit, it's not something I would have thought of myself!

The plugin was done by me, there's currently no way to make it easier which is a lack of the framework itself only if you do some heavy JS stuff 2. Last and most important thing, you didn't cover the creation of keys and how to exchange them, this is the most annoying part of WireGuard and that's why the handling of the plugin is so hard to understand.

Dear mimugmail. First of all - Hello! Pleased to make your acquaintance - and by all means I do appreciate all the work that you have in the development of WireGuard on OPNsense.

Further, I want to thank you for availing me of the knowledge that opnsense-code ports and pkg install wireguard and pkg install wireguard-go options are available. That saves me a ton of work.

I will work up a new tutorial which reflects those methods of installation and configuration of WireGuard on OPNsense. As far as your comment observation : Last and most important thing, you didn't cover the creation of keys and how to exchange them, this is the most annoying part of WireGuard and that's why the handling of the plugin is so hard to understand.

Well, this is where a whole confusing kettle of fish opens up at least for me and many others I am sure. Since the keys with Azire are managed by them you have to include the private key from the text file you downloaded and set as Tunnel Address the one in the config.

As I said - this is what had me pulling my hair out. Once again, I wish to thank you for all of your work and the information that you imparted to me regarding the options for installing wireguard and wireguard-go without having to go through the arduous task of building a package from scratch using FreeBSD Build Server.WireGuard is a simple and fast modern VPN.

Go back to tab Localopen the instance and choose the newly created endpoint in Peers. You also have a new interface Wireguard in rules, where you can set granular rules on connections inside your tunnel.

Your tunnel is now up and running.A virtual private network secures public network connections and in doing so it extends the private network into the public network such as internet. With a VPN you can create large secure networks that can act as one private network. Creating a single secured private network with multiple branch offices connecting to a single site can easily be setup from within the graphical user interface.

For remote users, certificates can be created and revoked and a simple to use export utility makes the client configuration a breeze.

I changed to Devil is in detail Before i forget: it would be great, to create an autorule in NAT for outbound connections. For the moment, i have it in hybrid mode, which would be unnecessary, if it would be there, when the services were activated. I dont like auto rules as they tend to break complex setups, sorry. That might be.

I wouldn't do that also not by default, but as it is in Proxy, giving the option to let it be done. So it's the decision of the user.

Congrats to today's golive as 1. Is there a migration from the package to the plugin? Don't want to just pull the trigger and break it SMF 2.
