8.4 The Address Mapping Screen

Use this screen to change your SBG's address mapping settings. Ordering your rules is important,
because the SBG applies the rules in the order that you specify. When a rule matches the current
packet, the SBG takes the corresponding action and the remaining rules are ignored.
