Apparently the 2.0 line of EdgeOS now supports ZeroTier

@jplee Very Interesting! Can you share how you got ZT setup on the edge router?

jplee

@VoIP_n00b I followed https://blog.kruyt.org/zerotier-on-a-ubiquiti-edgerouter/. It was pretty straightforward. Make sure you follow Part 2 of the guide as well. Now if I can just get the ER-X to route.

@jplee I would like that too

jplee

I have it working! I needed to NAT.

I also disabled routing to 192.168.50.0/24 on ZeroTier Central and unchecked "Allow Bridging". They aren't needed.

@jplee Interesting. I'll have to try it. As many details as you can provide would be great!

Why would you need to NAT? If you want the real IPs to work, you should be able to use them.

I don't NAT any of my other VPNs.

@Dashrender I couldn't get the ER-X to route LAN>ZT. NAT, although not ideal, did the trick for me. I'd love to hear if anyone has a no NAT solution.

Remind me what you setup is, I have a ER-X lying around I can set it up and give it a try this weekend.

@Dashrender Setup is outlined several posts above. Here

You don't need to set a NAT configuration if you set a route in the Zerotier web interface.

10.11.12.1/24 - (LAN)
192.168.1.1/24 via 10.11.12.1

The 10.11.12.1/24 is the Zerotier Network
The 192.168.1.1/24 is the Switch0 network for the ER-X

jplee

@dinge Do you have this working? It didn’t work for me. Remember, I’m trying to go from LAN to ZT, not the other way around.

dinge

@jplee From ZT to Lan I got this working without NAT or without a route configuration.

I could ping the ZT devices from my Switch0 LAN.

What I wanted was to be able to acces the complete Switch0 LAN from anywhere in the world when I am connected with a PC or phone in the same ZT Network.

@jplee This are the commands I used on a ER-X setup as WAN+2LAN2

sudo -i

curl -s https://install.zerotier.com | sudo bash

cd /var/lib

mv /var/lib/zerotier-one /config/scripts/

ln -s /config/scripts/zerotier-one

cp /opt/vyatta/share/perl5/Vyatta/Interface.pm /opt/vyatta/share/perl5/Vyatta/Interface.pm.backup

scp /Users/JohDoe/Downloads/zerotier-edgeos.tgz [email protected]:/home/ubnt
(from new terminal window)

tar -C / -xvzf /home/ubnt/zerotier-edgeos.tgz

connect zerotier (zerotieradress)

show interfaces zerotier

configure

set interfaces zerotier zt3jnycvh4 description ZerotierNetwork

@dinge I did that exactly. Can we compare configs? Here's mine:

OK peoples. I got this working both ways: LAN > ZT and ZT > LAN. The trick was to configure a source NAT, which you can only do via the command line. Along with destination NAT, a bidirectional NAT is setup. BOOM! Here's my config:

firewall {
    all-ping enable
