Hello,

I have location A B C conected with Zerotier and Wireguard at the same time. Problem is that when I enable Zerotier the Wireguard will stop working and only Zerotier is working. Do you have any idea what could be wrong?

I have noticed that in routes has Zerotier and Wireguard same Distance.

Im trying to learn the OSFP do you think that OSFP could sort this problem?

Thank you

Or you use Zero & Guard, or you use two ethernet cable, for the same source and destination, is the same.
Or you bond it, or you can use only one at the time... (ignoring how is selected the tunnel to use)

I was trying to change Distance in routes but Zerotier has distance 1 and can not be changed to distance 2. I would like to have Wireguard with distance 1 and Zerotier with distance 2...

WG probably works fine, it's just that if both endpoints are the same, the router chooses the shortest path first otherwise it picks the first one in the list (if they all have the same distance, scope etc, that is).

On way to control it is to use recursive routes and separate routing tables that is checked with a ping to find out if a route is active (ie if the wg/zt link is alive) Checkout this explonation with examples viewtopic.php?p=978539.

Hello Larsa,

thank you for helping. So OSFP will not help me?

OSPF works too!

Hard to know exactly here. You might want to statically assign your ZT address in /ip/address, and disable "Allow Managed" on zerotier1. That will stop the ZT route tables from populating /ip/route with any from my.zerotier.com controller, which is likely where the distance=1 things are coming from.

Also, ZT by default will try to find path down all routes. So might also create an interface list use by the zt1 instance that includes the specific interfaces you want ZT using. e.g. interfaces=all will cause ZT try to find path down a WG, likely not what you want.

Not sure OSPF going to magically fix the route table, or make this simpler. e.g. you can't push OSPF routes to the ZeroTier controller, so may still be managing a route table at my.zerotier.com depending on topology.

Larsa and Amm0.

thank you for your comments.

Firstlly I will learn OSFP to try to sort this out and in case it will not hepl I will not Allow Managed to Zerotier and try to set it by myself.
