Tunnel go down under light load

[ic32k]

Hello,

I've configured a ZeroTier network with 4 peers (zt-network2 was created for troubleshooting with complete different zt account), with this aprox distribution: `

`

I have connectivity with all the peers: PC1 to PClan PC2 to PClan PC3 to PClan

But connection between PC1 and PClan goes down if I try to make ligh use of the connection, I can browse a page hosted on PClan as long as it has no images or something heavier than a few lines, moment when the tunnel goes down. If i do the same with PC2 or PC3 there is no problem.

For troubleshoting I created another network with different user and connected to it PC1 and PC2, to check if there is any problem with PC1 connection, but while if I put traffic through the connection between pc1 and pclan it drops, the connection between pc1 and pc2 remains unchanged and the connection between pc2 and pclan is ok

Can someone helpme to start debugging this problem?

for any issues with opnsense we immediately suspect something like mentioned here: https://docs.zerotier.com/opnsense

it might be trying to use one of the zerotier routes to send zerotier traffic
