It's here for two reasons: + +1) There seem to be issues with large MTUs in the original tuntap code, + so we set up our zt0 tap with the correct ZeroTier MTU as the default. + +2) Lots of other mac products (VPNs, etc.) ship their own tap device + drivers that like to conflict with one another. This gives us no + choice but to play along. But we call our tap device zt0, which means + it won't conflict with everyone else's tap0. + +3) It's nice to call the device zt0, same as Linux, for consistency across + *nix platforms. Mac does not seem to support interface renaming. + +This will be placed in the ZeroTier home as a kext and is auto-loaded by the +ZeroTier One binary if /dev/zt0 is not found. It can also be auto-updated. + +See this page for the original: + +http://tuntaposx.sourceforge.net |
