Host names can be used only if
ELSA LANCOM
can resolve the names into IP
addresses. To do so,
ELSA LANCOM
has to have learned the names via DHCP
or NetBIOS, or the assignment has to be entered statically in the DNS or IP-
routing table. An entry in the IP-routing table can simultaneously assign a
host name to an entire net.
Filter list
The filter list is constructed of the object and rule lists. In doing so, the union
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
error message. When configuring filters manually, be sure to verify that the
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.
