Information About Completing Interface Configuration in
Routed Mode
This section includes the following topics:
• Security Levels, page 1-2
• Dual IP Stack (IPv4 and IPv6), page 1-2
Security Levels
Each interface must have a security level from 0 (lowest) to 100 (highest). For example, you should
assign your most secure network, such as the inside host network, to level 100. While the outside
network connected to the Internet can be level 0. Other networks, such as DMZs can be in between. You
can assign interfaces to the same security level. See the “Allowing Same Security Level Communication”
