INBOUND FILTER
By default, all incoming IP traffic that does not originate from the internal network is blocked when the firewall is enabled. Normal outgoing Internet
requests created by web browsing, email and other software you run will work as usual as the requests originate from inside your internal network.
The Inbound Filter allows you to create a filter rule to allow incoming IP traffic by specifying a filter name and at least one condition below. All of the
specified conditions in this filter rule must be satisfied for the rule to take effect.
To access the INBOUND FILTER setting window, click on the Inbound Filter button in the ADVANCED directory.
ADD INBOUND IP FILTER
Enter the Filter name and at least one of the
following criteria: Protocol,
Source/Destination IP Address and
Subnet Mask, and Source/Destination
Port.
Click on the Add/Apply button to add and
apply settings.
Note: This section only applies when the
Firewall is enabled.
