Model: ER605 (TL-R605)

Hardware Version: V2

Firmware Version: 2.2.6

Hi,

Archer ax23 openvpn TCP server with some IP cameras in its network (Tplink NC200-210-220-230)

ER605 as client + PC with ISPY video surveillance program.

RTSP streams work only in TCP mode, routing is working - I can Ping cameras, enter web interfaces. but cant see UDP video streams.

NOT on my pc nor on my mobile.

omada 605 blocks UDP traffic inside tcp tunnel?

TCP works:

I know that these cameras 100% support UDP streams.

If I connect to server directly from my PC with OpenVPN Connect everything works fine

If I connect to server from my Android mobile OpenVPN Connect , UDP streams also work in Tinycammon program

Hi @YuriyB

Thanks for posting in our business forum.

OVPN UDP or TCP only means how it communicates between two points. It does not matter what you have inside the tunnel.

You probably should Wireshark to find out if there is any traffic coming from the remote server as UDP. I don't think it blocks the traffic.

To further analysis this, I think you should paste some filtered Wireshark results to identify if the RTSP is even sending anything to the remote.

Hi @YuriyB

Thanks for posting in our business forum.

What does it look like when you set RTSP in UDP? IP should be specified for the devices involved.
