RTSP IP tables

RTSP forwarding
Enable IP forward in Linux.
echo 1 > /proc/sys/net/ipv4/ip_forward
Allow traffic to be NAT to dest device.
We specify the port the firewall is listening on with --dport
Then we specify the device behind the firewall and what port it’s listening on with --to-detination
iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.50.2:80
Use MPV to try connect through firewall. Generally RTSP is TCP.
We use the firewalls IP here.
mpv rtsp://admin:password@192.168.1.40:80/stream
