SunScreen EFS Release 3.0 Installation Guide

Upgrading from SunScreen SPF-200 to SunScreen EFS 3.0

You can upgrade the same machine that operates as your SPF-200 Screen to become a SunScreen EFS 3.0 Screen operating in stealth mode. You can also transfer your SPF-200 configurations to a new machine, and perform the conversion on the new machine.

Since SunScreen EFS 3.0 uses ordered packet filtering rules and ordered NAT mappings, you must to review your packet filtering rules after the conversion is complete to verify the filtering order is as you want. NAT mappings have changed considerably since the release of SPF-200. See the SunScreen EFS 3.0 Reference Manual for detail on NAT mappings.

Instructions for upgrading from SunScreen SPF-200 are in Chapter 6.
