Look at the RFC describing ICMP and you'll know what they mean,
for example a plain ping will be seen as :
ECHO Request : Type 8 - Code 0
ECHO Reply : Type 0 - Code 0
But some others like Destination port unreachable can get back
as : Type 3 - Code 3
Look at the exact Type/Code combination and see what they mean to
know if you should be worried ...

Subject: [FW-1] FW Log info -- question?
When looking at the FW logs --- when receiving a icmp -- what does"icmp-type
# icmp-code # " mean? -- should I be concerned?
Thank you,
