Packet Filters
The Packet Filter enables you to control what packets are allowed to pass through the router. There are two types of packet filter,
Outbound Packet Filter which applies to all outbound packets and the Inbound Packet Filter which only applies to packets that are
destined for a Virtual Server or DMZ host only.
Note: For further instructions on setting up MAC Level Filtering, please refer to the "MAC Control" section below
Outbound Filter:
To enable an Outbound Filter, tick the Enable tick box at the top of the page.
There are two types of filtering policies:
Allow all data traffic to pass except those that match the specified rules.
Deny all data traffic to pass except those that match the specified rules.
You can specify up to 48 filtering rules for each direction (Inbound or Outbound). For each rule you will need to define the
following:
Source IP address
Source port
Destination IP address
Destination port
Protocol: TCP or UDP or both.
Use Schedule Rule#
For source or destination IP address, you can define a single IP address (192.168.1.1) or a range of IP addresses (192.168.1.100-
192.168.20.200). Leaving these fields empty implies all IP addresses are matched.
For source or destination port, you can also define a single port (80) or a range of ports (1000-1999). Use the prefix "T" or "U" to
specify either the TCP or UDP protocol e.g. T80, U53, U2000-2999. No prefix indicates both
TCP and UDP are defined. Leaving this field empty implies all ports are matched.
The Packet Filter also works with Scheduling Rules, and gives you more flexibility on Access control.
Note: For further instructions on scheduling rules, please refer to the "Scheduling" section later in this guide
