2设备不在同一局域网内能否连接

mac 和 iphone 不在同一局域网无法连接
tail -n 100 ~/Library/Logs/QuickTUI/stderr.log | grep -i relay
13:15:40.062439 INFO relay agent disabled; no config on disk
14:02:17.234557 INFO relay agent disabled; no config on disk
14:23:58.164500 INFO relay agent disabled; no config on disk

Reproduce the connection attempt with the Mac and iPhone on different local networks, then inspect ~/Library/Logs/QuickTUI/stderr.log for the reported relay messages. Determine whether cross-network connection is supported and, if so, identify why the relay agent is disabled; done means the connection works or the limitation and required configuration are documented.
