Example 1: Filter Name : In_Filter1
Protocol : TCP
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 80
Dest. IP Address : NA
Dest. Subnet Mask : NA
Dest. Port : NA
Selected WAN interface : br0
This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP
Address/Subnet Mask 210.168.219.45/16 with a source port of 80, irrespective
of the destination. All other incoming packets on this interface are DROPPED.
Example 2: Filter Name
: In_Filter2
Protocol : UDP
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 5060:6060
Dest. IP Address : 192.168.1.45
Dest. Sub. Mask : 255.255.255.0
Dest. Port : 6060:7070
Selected WAN interface : br0
This rule will ACCEPT all UDP packets coming from WAN interface “br0” with IP
Address/Subnet Mask 210.168.219.45/16 and a source port in the range of
5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range
of 6060 to 7070. All other incoming packets on this interface are DROPPED.

MAC Filtering in the WUI.
Example 1: Global Policy
: Forwarded
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : NA
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC
Address. All other frames on this interface are forwarded.
Example 2: Global Policy
: Blocked
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : 00:34:12:78:90:56
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78 and Source MAC Address of
00:34:12:78:90:56. All other frames on this interface are dropped.
