Determine if you need to modify your firewall to gain access to systems from a wireless device.
When you use iSeries™ Navigator for Wireless, you will be accessing at least one of your systems from the Internet. If you access any of your systems from the Internet today, you probably have a firewall set up to prevent unauthorized access. Depending on your firewall configuration, you may have to modify your firewall setup to run iSeries Navigator for Wireless.
If you have never accessed your systems from the Internet and do not have a firewall set up, the following IBM® Redbook provides strategies for doing so in the chapters about screened host architecture and screened subnet architecture. See AS/400® Internet Security Scenarios: A Practical Approach®.
