Hey, I have setup netmaker on a VPS, and have connected clients to it. They all appear to be connected from the dashboard, but none of them can see or talk to each other, only to the server on the VPS. I cannot ping them. I have turned on udp punching. Am I missing anything obvious?

Are the nodes you are connecting behind NAT? Udp holepunching can help but not with cgnat. You could try making the node on the vps server a relay and relay one or more of the nodes.

Yes, they are behind NAT. That suggestion does work. Thanks! Can you help me understand exactly what the use-case for ude holepunching would be? I thought it was to help solve NAT issues.

Udp holepunching is intended to address NAT. The current implementation only works in some cases. It is being refactored for version v0.18.0 to handle more cases.

OK! Cool!
