3.5.1 Protocol filter parameters
The protocol table can accommodate up to 128 entries. Create an entry in
the protocol list for each protocol that requires special handling. Enter the fol-
lowing values:
D Name: freely selectable name for the filter entry [maximum 16 characters]
D DHCP source MAC: Enabling of DHCP address tracking.
D Yes: The rule applies if the source MAC address of the packet is listed
in the table under
Status > LAN Bridge Statistics > DHCP Table
as
an address which obtained an IP address using DHCP.
D No: The rule applies if this is not the case.
D Irrelevant: The source MAC address is not considered.
Note: If DHCP address tracking is enabled, any IP addresses usually en-
tered are disregarded. Please refer to ’DHCP address tracking’
→ page 92 for further information.
D Destination MAC address: The MAC address of the client to which the
packet is to be sent.
If no destination MAC address is entered, the filter is applied to all pack-
ets.
D Protocol: e.g. '0800' for IP.
If '0' is entered as the protocol, the filter applies to all packets.
D IP network and IP netmask: The IP address of the network mask to
which this filter applies. Only those IP packets whose source and destina-
tion IP addresses lie within this network are captured by the rule.
If no network is entered, the filter applies to all packets.
D Sub-protocol: e.g. '6' for TCP.
If '0' is entered as the sub-protocol, the filter applies to all packets of the
protocol entered.
D Start port and end port: e.g. both '80' for HTTP.
If '0' is entered as the start port, this filter will be applied to all ports of the
corresponding protocol/sub-protocol. If '0' is entered as the end port, the
start port becomes an end port.
Note: Lists of the official protocol and port numbers are available in the Inter-
net under www.iana.org.
D Action: Action performed for the data packets captured using this rule:
D Pass: The packet is forwarded on without change.
D Drop: The complete packet is dropped.
