Setting Up An Access Rule - D-Link DFL-260E User Manual

6.1.3. Access Rule Settings
If, for some reason, the Default Access Rule log message is continuously being generated by some
source and needs to be turned off, then the way to do this is to specify an Access Rule for that
source with an action of Drop.
Troubleshooting Access Rule Related Problems
It should be noted that Access Rules are a first filter of traffic before any other NetDefendOS
modules can see it. Sometimes problems can appear, such as setting up VPN tunnels, precisely
because of this. It is always advisable to check Access Rules when troubleshooting puzzling
problems in case a rule is preventing some other function, such as VPN tunnel establishment, from
working properly.
Example 6.1. Setting up an Access Rule
