Hello, I have a simple pfsense setup that does NAT for our office. I noticed that streaming videos take a long time to load on the clients.
Upon further investigation I learned that these videos use rtsp or mms protocols, which are composed of tcp control channel and udp data channel, ititiated by the server. Client requests video via tcp and server starts sending udp stream to the wan IP of our pfsense. Which of course knows nothig about how these udp packets relate to tcp session and calmly drops them. Client then has to time out and re-request video over tcp. I'm more familiar with linux iptables and I know there exist various helper modules which dig into the packets themselves to workaround such problems (ftp, irc dcc send, etc). I'm sure something of equal effect must be achievable on pf and pfsense. Can you point me in the right direction? -- Jure Pečar http://jure.pecar.org --------------------------------------------------------------------- To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
