guished. As an alternative to the alphanumeric keys, a 10-digit hexadecimal
value can be assigned.
In order to encode data communication, the same keys must be used for all
client stations and access points. Write down the assigned keys and store
them in a secure location.
The keys entered in the dialog box are only displayed when data is first input.
After closing the window, the values are protected from viewing via an
x-string.
4.2.3 Security for your LAN
You certainly would not like any outsider to have easy access to or to be able
to modify the data on your computer. A
ELSA LANCOM Wireless IL-11 offers
various ways of limiting access for incoming and outgoing router connec-
tions:
IP masquerading (also known as NAT/PAT)
Data packet filtering
Verification of incoming connections (callback to specified call numbers)
Firewall filter
The firewall filters of the LANCOM devices offer filter functions that can
apply to individual computers or the entire network. It is possible to set up
source and target filters for individual ports or port ranges. Furthermore, indi-
vidual protocols or any combinations of protocols (TCP/UDP/ICMP) can be fil-
tered.
As soon as a filter condition is met, a definable action can be triggered.
Two tables provide the means for setting up filters. The first, the object list,
is used to define computers, networks and protocols as objects. The second,
the rule list, is used to describe source, target and action based on individual
objects. The actual filter table is generated from these two tables.
As such, you do not need to create the filter list itself; and inconsistent
entries are thus prevented in the filter table.
