Hi, I am new to Linux IPTABLES. I have a windows box ( for Windows Streaming Media Server) behind the firewall (Iptables). I would like to redirect the external calls to my windows box for streaming video. But i am not able to configure it since my player says "your server may not support rtsp protocol" iptables -t nat -A PREROUTING -i xx.252.1225.27 -p tcp --dport 554 -j DNAT --to-dest 192.168.1.200:554 please help me in resolve this issue thanks & regards sundar
