Why do I get an error message “index 6 is not a valid index (max 5)“ when importing an own ASCII profile?

This is due to the fact that you are trying to access an entry that does not exist.
Each entry, for example a netfilter rule, has its own index number.
In this case, you are trying to access the 6th element of the list but only 5 elements exist.

  • Either try to correct the index of the entry appearing in the square brackets, e.g. [5] -> [6]

  • or add the correct number of elements to your ASCII file, e.g. with “netfilter.ip_filter.rule.add”
