We do see some UDP broadcast traffic, but we don't know if it is nmea data.
How is the YDWG set to UDP broadcast? iirc it only supports unicast, but i might be wrong.
I assume the YDWG logs into the peplink as a client? DHCP or static, and what is the gateway?
Can you view the routing table on the peplink? |
The Peplink is setup to hand out a static IP address over DHCP.
I fired up Wireshark and did a packet capture when on the same subnet and then the different subnets. Note the YDWG prefixes the sentences with 'YD'. I can see the 'YDGLL' in both packets.
