While playing a bit with NSM (Netscreen Security Manager), i found a nice bug!
you can't use some chars in the name of the firewall members:
for example: _ and [ or ], possible there are more!
the error you will see when trying to do a update is:
Exception caught during Update Device:
Failed during updating License info
Failed to process the database query. No record matched the query and nothing has been done.
Hope this help some of you!
