Question

mac 1 gateway: 10.9.11.254 mac 2 gateway: 10.9.23.254

mac 1 traceroute mac 2: traceroute 10.9.22.33

traceroute to 10.9.22.33 (10.9.22.33), 64 hops max, 52 byte packets 1 10.9.11.254 (10.9.11.254) 4.223 ms 1.258 ms 1.059 ms 2 10.9.22.33 (10.9.22.33) 15.504 ms 27.658 ms 17.130 ms

Neither mac 1 nor mac 2 found each other.

teleport version: v1.3.3 macos version: bug sure 11.2/11.4

AFAIK, Teleport only communicates in the same subnet and does not cross subnets if you don’t have a Bonjour/Zeroconf router/redirector that talks to both subnets… but I could be mistaken.

There several ways to configure Bonjour redirection and it will depend on your topology/configuration.

I hope this helps, but if I am wrong there will sure be someone else to point it out.

Cheers,

Confirming this - @laojianzi you need a Bonjour reflector (avahi works) or wide area bonjour (aka DNS-SD) configured across disparate subnets. Teleport works fine in this situation. @johndbritton I don't see this as a Teleport issue because Bonjour is its weapon of choice for service discovery.

This is expected and the provided explanations make sense.
