Examples for IP Filter Profiles
The pre-defined IP filter profiles “Internet incoming” and “Internet out-
going” can be used for standard Internet access. Profiles can also be
adapted to meet your needs, however. To distinguish the direction of
the connection request, TCP flags also can be taken into account.
Please see the recommended reading in the section “Additional Litera-
ture” from page 109.
