There is OPC UA GDS, i think it is not working with the asyncua library out of the box. We should have all the building blocks, but you have put them together, from the spec.

Thanks for your reply. I will look into the GDS
from opcua-asyncio.
hi, I understand the GDS is helping remote client to find the endpoints of local servers. These endpoints includes local ip address. But if the device hosting the local servers does not have a public domain, how can remote client really access these servers? Does the local device need something like "intranet penetration".
And is there an open source GDS avaiable?
from opcua-asyncio.
you need to expose it to the internet, like a webserver.
As alternative there is reverse connection. Now your server tries to connect to a client. The downside is, that the server must know the client address. Also this is currently not supported by asyncua.
A open source implementation is this https://github.com/OPCFoundation/UA-.NETStandard-Samples/blob/master/Samples/GDS/README.md
from opcua-asyncio.
