Regarding the issue of whether the server can be configured with multiple IPs on the same port

[jiangjunjie01]

I am using version 1.5.377.21.

My server is configured with 127:4840 and also configured with 192:4840.

<BaseAddresses>
<ua:String>opc.tcp://127.0.0.1:4840/GDX/UAServer</ua:String>
<ua:String>opc.tcp://192.168.3.13:4840/GDX/UAServer</ua:String>
</BaseAddresses>

The server can start normally

But when I used UaExpert to make a "GetEndpoints" request to 192:4840, I found that the "TranslateEndpointDescriptions" method did not return the "endpoints" list of 192:4840, but the "endpoints" list of 127:4840. This resulted in the incorrect PolicyId in the token passed by the client to the server for the "Activate Session" request initiated when the client connected at 192:4840.

Does OPC UA allow multiple IPs to be set on the same port? Is this issue a bug?

@jiangjunjie01 I think this issue should be fixed with the newest 1.5.378 update
