Host names can be used only if LANCOM can resolve the names into IP
addresses. To do so, LANCOM has to have learned the names via DHCP or

of sets of all filters defined by the objects and rules is formed.
Note here that incorrect input neither results in a filter being created nor an

filter you create does what you intend.
There are several ways of configuring firewall filters:
WEBconfig
Full configuration Setup IP router module Firewall
LANconfig
IP router Filter
Telnet
/Setup/IP-router module/Firewall
ELSA LANconfig provides a very convenient tool for setting up filters. Use the
following 'Filter' index card to define filter rules.
Note that configuring filters using LANconfig modifies the form of object
tables that have been set up using Telnet or WEBconfig.
