Yes, as long as the port is different.

Yes, but you bothered to mention the UdpListener part. I knew that, but left it out to avoid potentially confusing the poster.

Solution 2

Yes, it is possible as every tcp network packet has an IP, Port and Protocol-Identifier.
It is even possible to run a TcpListener and an UdpListener on the same port, too.
But you cannot bind two listener of one type (tcp or udp) to the same port.
