encryption has no security effect on data transmitted through wired (Ethernet)

connections.

• Conﬁguring WEP:

There are two levels of WEP encryption available, 64 bit and 128 bit. Se-

lect the desired level. Enter the pre-shared key in either hexadecimal

(0-9, A-F) format, 10 or 26 characters, or plain text (ASCII) format, 5 or 13

characters.

• Conﬁguring WPA:

With WPA there is only one level of encryption available. Enter the pre-

shared key, either as a 256 bit series of hexadecimal digits (64 characters)

or as a plain text (ASCII) pass-phrase (at least 8 characters).

Note: A plain text string is much easier to remember than hex keys, but it may

be easier to crack. Also note that the ASCII-text format may not be supported

by all wireless devices, since different manufacturers have developed different

ways of converting plain text. If you are experiencing difﬁculty, the hex key

format is supported by most vendors.

1.5.3 Firewall Setup

The GlobeSurfer 3G ﬁrewall has three pre-deﬁned levels of security. As default

the typical security is set, which blocks all trafﬁc that has been initiated by an

external (Internet) source, and allows all trafﬁc that has been initiated from

your local network.

Note: It is the origin of the request, not subsequent responses to this request, that

determines whether the incoming or outgoing trafﬁc is allowed or blocked.

To learn more about how to conﬁgure your ﬁrewall security parameters, please

refer to Section 5. If you wish to apply corporate-grade security to your net-

work refer to Section 5.11.

1.6 Additional Network Conﬁguration

GlobeSurfer 3G does not require further conﬁguration in order to start work-

ing. After the setup described in this chapter, you can immediately start using

the GlobeSurfer 3G to:

• Build a local network by connecting additional PCs and network devices

to the GlobeSurfer 3G.

• Share the Internet connection among multiple users and between all of

the computers connected to your local network.

• Share resources like ﬁle servers, printers, etc. between computers in the

local network.

• Control network parameters to, for example, set up Virtual Private Net-

works, LAN bridges and conﬁgure the security settings.

• View network status, trafﬁc statistics, system log and more.
