@CapitanBlack Thank you! that's is what I needed.
I didn't realize I could assign the same IP on pf1 and pf2 wg interfaces.
Now I need to test the failover.

@CapitanBlack
If I undestood correctly your setup, you need an outbound NAT rule for the HQ_LAN on the pfsense3 and BRANCH_LAN on pfsense1

It worked great! Thanks again!

Re: Does WireGuard work in a High Availability (pfsync mirrored firewall environment?)

Pulling up an old thread again. I am wondering if we cant have a wireguard setup that is aware of which CARP member is active, so we can have two firewall serving the same clients with seamless failover when one goes down.

Check out my post in Wireguard area - I have S2S Wireguard setup working in HA mode.

@pvswie Try copying it in HTTPS mode.

I am so sorry to have wasted your time but I've solved this, and it was complete and absolute muppetry on my behalf.

I had, many months ago, attempted to set this same thing up using an IPsec tunnel. The non-working IPsec tunnel was still set up on one of the devices...

My guess, it will come back

It was coming back today after rebooting host and start the pfsense in its VM.
At least i now fond a solution without reboot the host and the pfsense.
Solution was to go to Interfaces -> WGTun0 (tun_wg0) and disable the interface, safe that and the enable the interface gain.
So i gust the WGTun0-Interface will not every time comes up correctly after rebooting pfsense. Something went wrong.

@abstergo do a search in the forum, please. You'll see the topic came up a few times it's not something that can easily be done.

Seems setting up two separate tunnels and use OSPF is one option that doesn't involve scripting.

@flat4
Not sure -- but it's really strange how the routing / connection persists after initiating on my cellular network then "transistioning" to the guest wifi

@dennypage Okay thanks.

@michmoor Thanks but we have trashed it and will do OpenVPN even though it is slower, but more reliable and easier to troubleshoot.

To anyone having the same problem follow this guide
https://blog.matrixpost.net/set-up-wireguard-site-to-site-vpn-on-pfsense/

or in short, do not set an upstream gateway and set static routes as allowed ips.

@GTR_991 Hi guys,

I have the same issue. I'm running pfsense CE 2.7.2 and after restart I have to enable the wireguard gateway, then start the wireguard service.
I was thinking to do a script and add it to a cron job, but I couldn't find the right command that can enable the wireguard gateway. Any help is much appreciated. thanks.

Same here. Does not seem to do any harm but it just feels not right, having so much errors on an interface and not knowing why...

Thanks for the nice drawing. I will try again and see if it will work.

@The-Party-of-Hell-No

Hi,

Thanks for your reply. Yes I've set the tunnel up with all NAT rules in place, following guides, to the point of routing all traffic via the tunnel.

Just wasn't sure of the next steps and if a firewall rule would work.

I'll give that a go and see if it works as I'd like.
