Defining Sequence in IP Filtering Module

Hi,

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

But from ftp://ftp.openbsd.org/pub/OpenBSD/doc/pf-faq.pdf
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,
