Defining Sequence in IP Filtering Module


QNX does not support the sequence numbers while defining the IP Filtering rules.

But from
which is the openBSD version of ipfilter and looking quite similar to the QNX ip filter.

In BSD’s version there is a way to define port sequences in filter rules:

pass in on eth2 proto tcp from any port {1 2} to any port { 3 4 }

However, QNX does not allow this syntax.
Does any one have any idea how a list of ports can be defined, if at all?

Many thanks in advance,
