DI-1162/DI-1162M Remote Access Router
♦State – This is used to choose the routing decision applied to the frame. The three decisions are described:
1.Forward – This allows the routing of the frame, if it has met the criteria of the corresponding filter.
2.Drop – This drops (doesn’t allow routing for) a specific frame that has met the criteria of the corresponding filter.
3.Disable – This does not apply the protocol independent filter.
♦Interface – This applies the filter to a specific interface, either LAN or one of the WANs.
♦Offset – This defines the reference byte for the Length parameter (described below). The Offset is the number of bytes (octets) from the beginning of the first byte of the frame header, immediately after the preamble. The range of the Offset parameter is from 0 to 255 octets. The first byte in a packet has an offset 0.
♦Length – This is the number of bytes (octets) from the offset value (the Offset reference byte).
♦Value – This is a 16 digit, hexadecimal field, defining the actual bit values used to compare with the frame data, at the specified (Offset + Length) position.
♦Mask – This is a 16 digit, hexadecimal bit mask, used as an operand in the
IP Filter
The IP Filter is specifically an IP protocols filter, allowing you to, among other things, firewall your LAN, prohibiting specific packets from entering your LAN. It is necessary to have good knowledge of IP protocol before effectively configuring this filter.
Select an entry from above and hit <Enter>. This screen will be blank if an IP filter has not been configured yet.
