Perhaps a dumb question, but I need clarification on it.
Many times on the Internet you can find articles describing different configurations (VPN, access lists etc.) where they refer to the interface as "outside" or "inside" (these words are being used in the device configuration itself.) How is this associated with physical firewall interfaces. I do not see binding between physical interface and the "outside" and "inside" keywords. Does one need to define the interfaces like:
interface Ethernet0/0 nameif outside interface Ethernet0/1 nameif inside
or perhaps this is achieved by defining the "security-level" e.g: security-level 100 (for inside) or security-level 0 (for outside)?
Please clarify this for me.
Thanks, AL
