Virtual machine direct, VM host relay

Hi!

I am using zerotier to connect office computer from home.

In my home, there is an openwrt router[Device A] which has a dynamic assigned public IPv4 address and a Win10 LTSC PC[Device B] in lan.

In my office, there is a Win10 22H2 PC[Device C] within the company firewall, which is also a VMware host. And there is a [Device D]Win10 1703 VMware virtual machine in that PC. And is it possible the NIC issue?

And my current situation is that:

  1. The connection between A and C is direct. (5ms)

  2. The connection between A and D is direct. (5ms)

  3. The connection between B and D is direct. (5ms)

  4. The connection between B and C is relayed. (80-1000ms)

  5. And I configured the router setting where A is doing the router stuff. If C tries to ping B’s Lan IP, the latency is 5ms.

  6. The connection between B and another Ubuntu machine (physical machine) in office is also relayed! and the zt version of them is not showing when callin zerotier-cli peers.

  7. I have reinstalled Device B, there are very small chances the connection between B and C would become direct somehow before I reinstalled.

  8. I have reinstalled the zerotier in both B and C, no much help.

  9. I am very certain the direct connection between B and C is possible to build, since both parsec and todesk can make it.

  10. There is a very very peculiar situation, when I restarted the ZeroTierOneService in B. The first a few seconds the latency between B and C is 5ms, and it gradually increases to a relayed latency.
