[SonicWALL]- Rule 0?

[Intelliware Administrator]

I am trying to ping from a DMZ address to a LAN address.  I have a route set in my router that Dest=192.168.155.1/24 Gateway=204.155.155.125 which is the public IP address of the SonicWall.  In the SonicWall Log  I get ICMP Packet Dropped 204.155.155.111, 8 DMZ  192.168.155.1, 8 LAN  "Ping" Rule 0.   Where/what the heck is Rule 0?  I have rules that allow traffic from the DMZ to LAN but it still fails.  Any help would be appreciated.   Thanks, Kevin M.
