I want to connect B and C to each other through A node, and then they can transfer files to each other.
when i execute the commandipfs swarm connect /ip4/1.14.49.178/udp/4001/quic-v1/p2p/12D3KooWDzkEohDABVk6fUMRENaX1CWUcLLKLrew4X5aB7NvX6eZ/p2p-circuit/p2p/12D3KooWQy7qrxKo918uTPmVMnewDGHmUzMFL8MHcWJTfZoZhXCr but there is no result, no error and no connection to the target node
When I do not specify the relay point, the two points behind NAT can connect to each other and transfer files
