23.1 Legacy Series / Re: Zerotier stopped working after upgrade to 23.1

« on: February 22, 2023, 08:38:43 pm »

Just to answer my own question, I resolved this.

I had the wrong configuration in 22.11 but things worked anyway. When upgrading this configuration was broken.

In the interface settings for zerotier I had set the subnet dropdown to "32". This worked in 22.11 (the zerotier program must have overridden the routing table)

I corrected this to "16" and the routing table is now correct, and traffic is flowing. I am guessing this is down to a change in how BSD manages the network stack.

I have tried a reinstall, and recreated the interface with the same result.

This seems to be a routing table problem, the default root for the interface is being deleted by something in Opnsense.

My zerotier network happens to be 172.24.0.0/16

If I stop and start the zerotier service, for a few seconds I see this route via netstat -nr

Code: [Select]

172.24.0.0/16      link#11            U      zt15b2a3
172.24.15.180      link#11            UH          lo0

And everything works has expected.

Then traffic stops and this route has been removed from the routing table (I make no other changes). Only this entry is left

Code: [Select]

172.24.15.180      link#11            UH          lo0

I have a "ZERO" Interface created, and enabled. The static IP is set (following the instructions here: https://docs.opnsense.org/manual/how-tos/zerotier.html)

If I add the route manually with

Code: [Select]

route add -net 172.24.0.0/16 -interface zt15b2a3pottmrd

Then things start working again!

What would automatically reset the link routing table?

23.1 Legacy Series / Zerotier stopped working after upgrade to 23.1

I just upgraded to 23.1 and Zerotier no longer works from my router.

I have both Wireguard and Zerotier installed as separate interfaces. On 22.11 this worked flawlessly.

After the upgrade Wireguard works fine, Zerotier does not connect even though the zerotier-cli shows connected.

Something I noticed is that there is no zerotier IPv4 interface listed in the routing table and it is not listed in System -> Gateways -> Single either.

I cannot reach the Zerotier IP of the router from other Zerotier hosts.

On the Zerotier console the router shows as "up".

zerotier-cli thinks it is connected:

Code: [Select]

# zerotier-cli info
200 info xxxxxxxxxx 1.10.2 ONLINE


Plugins installed:

Code: [Select]

os-zerotier version 1.3.2_4

zerotier-cli reports

Code: [Select]

# zerotier-cli -v
1.10.2
Has anyone else seen this issue and figured out how to solve it?
