I made a WireGuard package for pfSense

svenruben

Hey Ascrod, thanks for your great work!!! would you be able to make that work for a clustered environment (pfSense High Availability)? and a second idea: would it be complicated to make your WEB-GUI working for more than one interface?

thanks again! Cheers, Sven.

Nice work ;)

I have A Netgate SG-3100 running 2.4.5-RELEASE-p1 (arm) built on Tue Jun 02 17:45:24 EDT 2020 FreeBSD 11.3-STABLE

Is there A install for that?

I'm now running this error.

pkg: wrong architecture: FreeBSD:11:amd64 instead of FreeBSD:11:armv6

Thanks in advance.

Hi all - A question on routing with Wireguard

I have Wireguard setup pfSense acting as a VPN concentrator (Road Warrier) and also as a Site to Site connection.
From my local pfSense I want to be able to use the site-2-site connection , reach the remote Wireguard server and then break out to internet from there. I have successfully configured this.

To get this to work I use 0.0.0.0/0 in the allowed-IP of peer-config in the pfSense.

As you you would imagine this also adds a default route to the pf routing table (with a higher pref than the local route ) and all LAN traffic then starts flowing over the site-to-site tunnel. What I want to get to is use this site-2-site tunnel for only certain LAN devices and not all. So for instance my appleTV behind pfSense could use this and break out to the internet from the remote Wireguard server.

What have I have explored

Tried to change the gateway of the other devices to the WAN_DHCP - this breaks a few things for me
Tried adding Table = off in the peer config to prevent this route from getting added. Does not work
Adding specific IP's to the peer config instead of default will not work as administrative headache of maintaining those is too high.

PFsense Wireguard config

[Interface]
Address = 10.100.100.1/24
ListenPort = 51820
DNS = 192.168.11.5
PrivateKey = xxxx

[Peer]
PublicKey = yyyy
AllowedIPs = 0.0.0.0/0

Route Table after activating Wireguard Site to Site tunnel.

@ab5g the config is different for pfsense and the peer. By specifying 0.0.0.0/0 on pfsense you are telling that it can send all traffic down the tunnel. That's not what you want, you only need traffic destined for your client/peer to go down the tunnel.

On pfsense the AllowedIPs should be the one IP address the client/peer is using. Mine looks like this:

The client/peer config on the other hand would look something like this;
[Interface]
Address = 192.168.xx.yy/32 #make sure this matches the IP in the pfsense config
DNS = 192.168.xx.1 #you can make this an interface on the pfsense (even the tunnel interface, just make sure the resolver is listening on the interface
PrivateKey = obfuscated

[Peer]
Endpoint = [pfsense public ip]:[pfsense wiregaurd port]
PublicKey = obfuscated
AllowedIPs = 0.0.0.0/0

@lucas_nz

Thank you for replying. The reason I have a 0.0.0.0/0 on the pfSense WireGuard Peer is because I want certain LAN devices (like AppleTV) to use the Wireguard tunnel and exit to the internet from the remote site.

Remote IP is 10.100.100.50
Remote LAN is 192.168.29.0/24

So if I specify allow only the 2 IP above in my peer config on pfSense- I will only be able to reach the remote LAN, but not break out to the internet from remote Wireguard server.

Unfortunately with a 0.0.0.0/0 as the WireGuard Peer, it creates a more specific route in the routing table, forcing all LAN traffic to flow to the remote site instead of certain LAN devices

@ab5g
I see. I don't have experience on an outbound "VPN" like this with wg. But I note others in this thread have had the same problem. I'm not sure if a resolution was found.

@trevorstuart

You can goto System>Routing and Add a new Gateway pointing it to the new WireGuard interface. You can then use it like a a normal gateway. The gateway will not appear automatically.
After you create a gateway, I ran into some routing issues related to my setup that I have explained in a post above.

@lucas_nz

Solved it. Added the following configuration to the tunwg0.conf file ( can be done through the command line or the GUI).

PostUp = route delete 0.0.0.0/1

This deletes the route from the routing table, allowing pfSense to route based on source IP's.

@burntoc I'm in the same boat.

I'm on an SG-5100 running 2.4.5-RELEASE-p1 which is supposed to be the most up to date (as of this post). Anybody this out? I'm assuming I shouldn't mismatch.

Your error is different fro the burntoc's. Your error is simply implying that the kernel we are running is 11.03 while the package is for 11.04 (latest). You can go ahead and ignore the mismatch to continue (if you wish to - I did the same).

Looks like the kernel package has just been merged into mainline for 2.5.0. Hope we see it functional out of the box by next release! https://redmine.pfsense.org/issues/8786

Project changed from pfSense Packages to pfSense
Category changed from New Package Request to VPN (Multiple Types)

Hello,

Anybody know how to completely remove this prior to updating to 2.5? By simply removing the packages, does it also remove the settings from the configuration or are there remnants? And if there are, do they cause a conflict or any errors?

I'd be curious to hear form someone who was running this (awesome, btw) homebrew package and who upgraded to 2.5. Did it work out? Did you have to manually delete things from the config and restore?

Things like that. I'm trying to figure out if I can just upgrade or if I will need to start from scratch (don't want to do that...).

Thanks!

@bla
I did that - I ended up removing the package and upgrading to 2.5. Unfortunately it did not work out very smoothly for me. I had some issues with packets 'disappearing'. I don't know if it was related but I ended up doing a clean reinstall. You can read more about the packet disappearing in my post in the Wireguard subsection. YMMV.

@ab5g Thanks for chiming in (even though it's not the reply I was hoping for) ;-)

Now that WG has been disabled in 2.5, is this package still available for use in 2.5? Can it still be used in v2.5?

Would appreciate experiences before i take the plunge.
