The first command that I executed in figure was to change the hostname of
the appliance to asa and a domain name of rumyittips.com. Following this, I configured a Privilege EXEC password of rumyittips.I then configured the three interfaces,
assigning them logical names, security levels, and IP addresses, and enabling them.
Once IP was configured, I wanted to be able to SSH on this appliance, so I assigned
a User EXEC password of rumyittips,generating the public and private RSA keys and
allowing any internal computer SSH access. Finally, I saved the appliance configuration—
remember that you can execute the write memory command at either Privilege EXEC
or Configuration mode.
You will actually need to do quite a few more things to pass traffic through your
appliance, like setting up routing, configuring translation policies (if necessary), setting
up ACLs, and many other policy configurations.
