Bob, Thanks. But, TCP doesn't need a NAT helper because only UDP uses an anonymous port that the server needs to connect back to the client on. The argument is that UDP give better performace which is why I am trying to get a 2.4 NAT helper for Real Player. Anyone know of anyone else working on the problem? ICQ would is another helper I am looking for. Anyone working on that? MH
