Hi,
I check for protocol 58 and then ask for icmp type and code. Type and
code then are 0 sometimes. I cannot send a dump because of privacy
restrictions. I am testing in a productive network.
I set up a testing environment and try to reproduce the type and flags
set to 0 while protocol is 58.
I'll send a dump as soon as I reproduce the problem within my test network.

Cheers,
Dominik
