2. Filter Name : In_Filter2
Protocol : UDP
Source Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 5060:6060
Dest. Address :192.168.1.45
Dest. Sub. Mask : 255.255.255.0
Dest. Port : 6060:7070
This rule will ACCEPT all UDP packets coming from WAN interface
mer_0_35/nas_0_35 with IP Address/Sub. 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 Filtering:
These rules help in the filtering of traffic at the Layer 2. MAC Filtering is only
effective on ATM PVCs configured in Bridge mode. After a Bridge mode PVC is
created, navigate to Advanced Setup -> Security -> MAC Filtering web page.
Global Policy:
When set to Forwarded the default filter behavior is to
Forward all MAC layer frames except those explicitly stated in the rules.
Setting it to Blocked changes the default filter behavior to Drop all
MAC layer frames except those explicitly stated in the rules.
To setup a rule:
Protocol Type: Can be PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI or IGMP.
Destination MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with
this particular destination address will be Forwarded/Dropped depending on
whether the Global Policy is Blocked/Forwarded.
Source MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this
particular source address will be Forwarded/Dropped depending on whether the
Global Policy is Blocked/Forwarded.
Frame Direction:
LAN <=> WAN --> All Frames coming/going to/from LAN or to/from WAN.
WAN => LAN --> All Frames coming from WAN destined to LAN.
LAN => WAN --> All Frames coming from LAN destined to WAN
User needs to select the interface on which this rule is applied.
Examples:
1.
Global Policy: Forwarded
Protocol Type: PPPoE
Dest. MAC Addr: 00:12:34:56:78
Source MAC Addr: NA
Frame Direction: LAN => WAN
WAN Interface Selected: br_0_34/nas_0_34
Addition of this rule drops all PPPoE frames going from LAN-side to WAN-side with a
Dest. MAC Addr. of 00:12:34:56:78 irrespective of its Source MAC Addr. on the
br_0_34 WAN interface. All other frames on this interface are forwarded.
