9.6.7 Security
9.6.7.1 Firewall
On the Configuration > Security > Firewall page you can select the
desired security level for the built-in firewall.
To simplify the configuration you can select a general security level (Low,
Medium or High) for the firewall.
Low does not imply a low level of security, but differs from High in that High
implement more restrictive rules, allowing fewer programs to be able to
pass through the firewall. Even the Low setting offers a high level of
security since the firewall inspects all traffic and blocks attacks before they
can reach your PCs.
If you select Off, the firewall will be disabled and if you select Block, all
traffic to/from the Internet will be blocked.
You can click the link The table of default policies for various security
levels at he bottom of the page to see which applications are allowed for
the different security levels:
