All our Generation 5 boards implement 4 ethernet listeners

TCP 1 - Port 52801 TCP 2 - Port 52802 UDP 1 - Port 52801 UDP 2 - Port 52802 Each port can support multiple connections and all four ports can be operated simultaneously without threading issues. However, there is no guarantee that someone connecting to one port is not going to overwrite data written from another port or a connection on the same port. It is possible to turn off individual ports through the EEPROM, but there is currently no mechanism to restrict the number of simultaneous connections.
