Hello all I a have setup udpcast in a classroom at a Secondary School to distribute CDs and whole directorie trees, and it works like a charm, except for a minor nuissance. Everytime I want to use udpcast I have to disconnect from the 3com-812 router that serves as a gateway. When I try to send anything with the gateway connected there is an extremely low transmission with errors el al. As soon as I disconnect the router the throughput goes up to 70-90 Mbps. Does anybody have any hint? Thank you all -- Saludos Paco Cruz --------------------------------------------------------------------- "If you have an apple and I have an apple and we exchange these apples then you and I will still each have *one* apple.
