D-Link DI-206 manual Multiple Home Configuration

DI-206 ISDN Remote Router

2.drop – This drops (doesn’t allow routing for) a specific packet that has met the criteria of the corresponding filter.

3.disable – This does not apply the IP filter.

•Interface – This applies the filter to a specific interface, LAN or one of the ISDN interfaces.

•Protocol Type – This is a protocol identifier, as assigned by the Internet Assigned Numbers Authority (IANA). The values of this identifier are described in RFC-1700. This router supports the following:

1– This is Internet Control Message (ICMP), defined in RFC 792.

6 – This is Transmission Control (TCP), defined in RFC 793. 17 – This is User Datagram (UDP), defined in RFC 798.

•Src IP – This is the source address in the IP header of this packet.

•Src Netmask – This mask is bit-wise AND’d with the source IP address and bit- wise AND’d with the IP address of the incoming interface. The two results are then compared.

•Src Port – This is the source port , in the TCP or UDP header, of the packet.

•Src Port Operation – This comparison operation is applied to the source port (the Src Port parameter) value, of the TCP or UDP header.

•Dst IP – This is the destination address in the IP header of the packet.

•Dst Netmask – This mask is bit-wise AND’d with the destination IP address and bit-wise AND’d with the IP address of the incoming interface. The two results are then compared.

•Dst Port – This is the destination port, in the TCP or UDP header, of the packet.

•Dst Port Operation – This comparison operation is applied to the destination port (the Dst Port parameter) value, of the TCP or UDP header.

•ICMP Type – This is the type field, in the ICMP header, used to identify a particular ICMP message.

•ICMP Code – This is the code field, in the ICMP header, used to further specify the ICMP type.

•TCP Flag – This is a hex number, representing the six flag bits in the TCP header. The value range is from 0 to 3F.

Multiple Home Configuration

Besides the IP address assigned to the LAN interface in the Network Configuration menu, the LAN may have up to 3 additional IP interfaces. These additional IP interfaces are referred to as MIP1 to MIP3. This type of configuration is known as a multiple home configuration.
