Is this a known thing for

  • Hello Michael@BWC,

    I could not find anything like this reported for version. Best thing to try will be doing a packet capture and checking if the packets are reaching SonicWall or getting dropped due to some reason.

    partly my fault, I did not realized the IP addresses are different between the LAN subnets.

    Two subnets on two interfaces (X0, X3) are part of the LAN Zone, Interface trust is enabled. I was running a ping from subnet A to subnet B monitoring addresses, this is only working for the primary (currently active) address, not the secondary. The icmp request just got lost, no block no nothing. Even a LAN-LAN ping rule for management traffic makes no difference.

    But never mind, pinging from within the same subnet is working fine, it's just a glitch.


  • Got it. Thanks for sharing Michael. 😃
