Hello, I am trying to get the RealProducer to upload a live broadcast to my RealServer. If I connect to the internet from my Win95 box thru a dial-up connection, everything works fine. However, if I connect thru my Linux Masquerading box, it dies after a minute or two. I've looked all through RealNetwork's FAQs on firewalls, and have tried a bunch of stuff, all to no avail. Has anyone else done this? I basically just need the IPCHAINS commands to let this stuff through. Their website has very limited info available at: http://service5.real.com/solutions/RVS00038.HTM The encoder is set to use port 4040, which they do not mention. Help! Bob
