Strange DNS traffic
i am trying to optimiz my lab environment and at the moment it is DNS is am working on.
Sonicwall is configured as proxy, external interface is 192.168.8.3.
Router is 192.168.8.1
What is strange - packet capture is showing this packets:
Ether Type: IP(0x800), Src=[2c:b8:ed:a5:12:31], Dst=[2c:b8:ed:a5:12:31]
IP Packet Header
IP Type: UDP(0x11), Src=[10.0.0.1], Dst=[192.168.8.3]
UDP Packet Header
Src=, Dst=, Checksum=0x1397, Message Length=138 bytes
Consumed, Module Id:48 2:2)
Seems like IP 10.0.0.1 is sending a DNS request to the external interface.
The MAC for sender and receiver is identical?
So i thought there might be any config in the firewall using 10.0.0.1 on X1 interface but there's none i can find in the tech support file.
Any idea what is causing this traffic?
