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 LAYER FILTER
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in
Bridge mode. After a Bridge mode connection is created, navigate to Advanced
Setup
Security
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.
