We are currently facing a network issue with one of our Teltonika routers located at a local site (LAN IP 10.10.43.1), which is connected to cameras and a lidar. The router is also connected via the WAN port (10.9.5.X) to a fiber router, allowing access to a remote edge server.
On this edge server, we have an application that performs image processing from the cameras connected to the Teltonika router. We are able to access the camera interface from the edge server, thanks to the network configuration rules on the Teltonika router. However, we have been unable to access the lidar’s (IP 10.10.24.99) cloud points from the edge server, which is a critical issue for our project.
After investigating, we observed that no UDP packets are being received on port 2368 (verified using tcpdump) on the edge server, whereas these packets are present on the LAN at the local site. We can also visualize the traffic on the router, but the packets do not seem to be forwarded to the WAN.
To resolve the issue, we installed a UDP broadcast relay and directed the traffic from the LAN to the WAN. However, this solution has not been successful.
Given the impact this has on our project, we request your assistance in resolving this issue as soon as possible. Could you suggest any additional configurations or solutions to ensure the proper forwarding of UDP packets from LAN to WAN?
We greatly appreciate your prompt attention to this matter and look forward to your response.
