Hello

We have Dart.PowerTCP.Sockets version 1.1.1.4
We are using below process for two servers listening using same udp port.

here:-
->udpServer = new Dart.PowerTCP.Sockets.Udp

->udpServer.Open(UdpPortToListen)

->udpServer.Socket.SetSocketOption(Sockets.SocketOptionLevel.Socket, Sockets.SocketOptionName.ReuseAddress, True)

this way, we have got an error
"Only one usage of each socket address (protocol/network
address/port) is normally permitted"

so is there any other alternative way to solve the issue?
If possible then please inform me with details

Thanks

Hello,

Have you tried setting the Udp.Socket.ExclusiveAddressUse property to false?

Please note, when binding multiple processes to a single port, only one will receive any message; this is due to the Windows IP stack, and not our control.
