Hello there, glad I was able to answer some of your questions, here are a few clarifications:
I retract what I’ve stated regarding passthrough + ZeroTier, as it seems like it works, but there are a couple of niche things that could cause it not to work, which happened in my case. Kindly refer to this thread for an answer, more specifically, to Janmiguel’s answer where he showed the entire configuration. He mentions changing subnets for the VPN to start functioning again, try that, personally, it helped me.
Regarding the bridging, I might’ve misunderstood what you’ve initially requested, could you elaborate a little more on what you’re trying to configure/bridge between?
RMS does work in Passthrough mode. After enabling it, it might take a few minutes for the device to regain connectivity to the service, but it works.
Regards,
M.
