ip filtering /NAT in qnx

hello
im new to qnx and was wondering how QNX handles ip/port filtering?

i set up samba but cant access the share because i believe that the ports samba needs are being filtered out.

does it use Ipfilter? ipchains?. documentation on this is somewhat scant.

thanks for any help

There is IPFilter for QNX, but it is not loaded by default.

By default, QNX do not block any port. After you start Samba, check “pidin” to see daemons are running, “netstat -na” to see if the port is listening, and probably /var/log/syslog (you need to
setup and start syslogd first) for any possiable error message.
