If there is no payload traffic in the VPN, there should be no reason to query for IP addresses. And if tinc switches do query for addresses without cause, why would they query for each possible address individually? When an entire subnet is assigned to one node, shouldn't that suffice? Even if two nodes had the same subnet assigned to them, a switch should simply multicast to both peers to find the target of a connection. Am I missing something important?

<div>I suspect your /64.. try giving a single address to two seperate machine so one single addresses for each. /32 . Then check your traffic. Tinc is a mesh network. If you give it millions of addresses. Then its probably checking each one.</div>

<div>Good evening,</div>
<div> </div>
<div>all of my servers where set up fresh with no other applications running besides tinc and my ssh sessions. I just double checked and those are the two only processes on my machines that have active sockets. Additionally, the SSH sessions do not go through the VPN, but are set up directly to the machines. Does tinc provide a way for differentiating between between meta and payload traffic?</div>

<br>
indeed - I never noticed an unreasonable amount of tinc management traffic<br>
with any of my setups.<br>
<br>
How exactly did you verify, that tinc meta traffic is really the culprit?<br>
Did you compare the traffic over your uplink interface with the traffic<br>
over the tinc interface?<br>
Maybe there is just a huge amount of payload traffic exchanged between the<br>
nodes over the tinc VPN?<br>
Since you are using "switch" mode, this could even be broadcast traffic.<br>
<br>
Cheers,<br>
Lars<br>
