Firewall dropping traffic to LAN X0 IP from Local Host on same LAN

Escko

I'm having an issue with a Zebra Scanner (Android) unable to establish a connection to remote host computer. Packet seems to drop on SonicWalls X0 IP 10.10.10.1 from Host 10.10.10.3 over port 853. I'm stumped....

What is listening on TCP port 853 on the Sonicwall? Nothing, which is why it is dropped.

Did you accidentally enable one arm mode on port X0?
