4.1.7 Firewall Settings
The firewall settings provide options for limiting or denying
access to and from the system. If you do not configure this
section, the firewall is inactive and access is unlimited.
In the following example, only port 4445 allows incoming con-
nections from the IP address 192.168.1.10. All others will be
blocked
Example 4.7
pppoe0
configuration
[pppoe0]
PppoeIf=emac1
User=user
Pwd=pwd
AuthProto=pap
Route=0.0.0.0
Make sure you configure the firewall rules carefully. The
rules are processed from top to bottom. If you use the op-
tion quick , you will break the sequence. We recommend
that you put the most restrictive rule at the end of the con-
figuration.
