I want to check if a client can access a server via rtsp://192.168.1.5:554. As you can see the rtsp protocol and port #554 must be open and working on the server.
Can I add
iptables -A INPUT -m state --state NEW -p tcp --dport 554 -j ACCEPT
but the protocol is specified as tcp. changing that to -p rtsp
doesn't work either.
Any idea on that?
