I have been asked to set streaming so some of our users can use real audio
and rtsp.
I have enable the rtsp proxy app and am running BM 3.8sp1 which goes through
a BM3.7sp2 firewall.

Do I need to also put rules on the firewall for all the RTSP ports ?

Looking at real audio it reconds you can run it over port 80 so surely no
proxies will be needed or rules as port 80 proxy over http is already

But I can't get it to run just using port 80.

What should i do to the clients and the backend.

All servers are nw6 sp3 or 4
