Need some advice on RTSP and firewall rules?
I am trying to stream Youtube videos with my Nokia N95 mobile via WLAN. I am running pfSense version 1.2 embedded on an 3 nic alix platform. I am not able to watch videos on youtube using my mobiles RealPlayer.
It seems that RTSP/RTCP needs some kind of port forwarding??? How can I solve this issue? I could also provide a packetcapture.cap
I think the easiest way would be to use a RTSP Proxy… is anyone aware of a free public rtp proxy?
I have now configured my mobiles RealPlayer port range from 32000/udp - 33000/udp. Then I set up a port forwarding rule from the wan interface for this port range to 192.168.3.101 (mobile). Regarding to tcpdump there is some packet flow, at least at the pfSense DMZ interface. But somehow the packets do not reach my mobile. My linksys router is configured in "router" mode… IP 192.168.3.101 is pingable from the DMZ interface...
19:13:34.164639 IP 220.127.116.11.10580 > 192.168.3.101.32140: UDP, length 223
19:13:34.202013 IP 18.104.22.168.10580 > 192.168.3.101.32020: UDP, length 193
So whats wrong here?
Update 1: I have also tried to setup a telnet natting to my laptop (192.168.3.100) for testing purpose. The telnet service is reachable from the pfsense box but not from wan… I am out of ideas...
Update 2: The telnet natting is working... seemed to be an issue with the nmap-online.com
Changing the ports from 6970/udp - 9999/udp did the trick…. dont ask me why.... ??? it may be an issue with Nokias Realplayer...
