Chapter 3: Getting Started
38 WatchGuard Firebox System
You can remove the blue serial cable from the Management Station and
Firebox after the QuickSetup Wizard is completed.
Entering IP addresses
You generally enter IP addresses into fields that resemble the one below.
When typing IP addresses, type the digits and periods in sequence. Do
not use the TAB key, arrow key, spacebar, or mouse to jump past the
periods. For example, if you are typing the address 172.16.1.10, do not
type a space after you type “16” or try to position your cursor past the
next period to begin typing “1.” Instead, type a period right after “16,”
and then type “1.10.”
If your address has a network mask, use slash notation to enter it. In slash
notation, a single number indicates how many bits of the IP address
identify the network that the host is on. A netmask of 255.255.255.0 has a
slash equivalent of 8+8+8=24. For example, writing 192.168.42.23/24 is the
same as specifying an IP address of 192.168.42.23 with a corresponding
netmask of 255.255.255.0. The following table shows network masks and
slash equivalents.
