Preface

Data Formats

As you configure and manage the system, enter data in these formats unless the instructions indicate
otherwise.

IP addresses

IP addresses use 4-byte dotted decimal notation; for example, 192.168.12.34 . You can omit leading
zeros in a byte position.

Subnet masks and wildcard masks

Subnet masks use 4-byte dotted decimal notation; for example, 255.255.255.0 . Wildcard masks are
the reverse of subnet masks and use the same notation; for example, 0.0.0.255 . You can omit leading
zeros in a byte position.

MAC addresses

MAC addresses use 6-byte hexadecimal notation; for example, 00.10.5A.1F.4F.07 .

Hostnames

Hostnames use legitimate network host or end-system name notation; for example, VPN01 . Spaces are
not allowed. A hostname must uniquely identify a specific system on a network.

Text strings

Text strings use alphanumeric characters, upper- and lower-case. Most text strings are case-sensitive; for
example, simon and Simon represent different usernames. The maximum length of text strings is
generally 48 characters.

Filenames

Filenames on the VPN Concentrator follow the DOS 8.3 naming convention: a maximum of eight
characters for the name, plus a maximum of three characters for an extension. For example,
LOG00007.TXT

Port numbers

Port numbers use decimal numbers from 0 to 65535 with no commas or spaces.
xl
is a legitimate filename. The VPN Concentrator always stores filenames as uppercase.
