Anyone using ZeroTier? Can it be used with dual WAN for vpn failover?

[kapara]

I am curious if ZeroTier can be used with dual wan for vpn failover.  Does anyone have any experience with this?

Really no one has used ZeroTier?  is it a bad product?

Is David Harrigan dharrigan@gmail.com a developer at OPNsense?  I tried emailing him but no response and no response from the community.  Can anyone give any insight into this?

He pinged me last time via IRC, maybe you can have a look there, but ZeroTier is quite unmaintained (as it's the software itself too).

I use ZeroTier but not with dual WAN yet. I like it, it works well and is reliable. But cant comment on dual WAN. In theory it should work.

Great to hear.  Some of my reading said it required a lot of ram.   Can you tell me more about your implementation?  I am looking at Point to point between 2 firewalls.  Current firewalls have 8GB ram

I have posted a job on upwork to get assistance with this.  If anyone here is interested I am happy to pay $150 an hour for assistance.  But this must be something you have previously done.  Site to site vpn over ZeroTier.

I am getting ping replies from the ZeroTier IP assigned ot the remote interface but nothing from the remote LAN even though routes have been added to ZeroTier and I think I have added all required rules.

On wan allow any from ZT Net

And on ZT interface allow to any

I also get 304 ping timeouts regularly.

So it started working!  I am now connected site to site over ZeroTier.  Now to test VPN failover by disabling the remote primary wan connection!  There is hope!
