My goal is to redirect all UDP traffic on port 10000 to the "serial" port on the CentOS Guest system. To do this, I created a host pipe with Virtual Box and specified the path \\.\pipe\mypipe. I downloaded this program called TunnelEx which supposedly could redirect traffic and should do exactly what I need, UDP to named pipe. However, TunnelEx fails to connect to the named pipe created by Virtual Box. Has anyone used this and can give me tips to make this work? What about other methods that I can use to accomplish the same goal?
