Subtype Filters
You can define output filters that restrict customized frame subtypes
that can pass through an IP tunnel. Frames can be filtered by the DIX,
802.2, or 802.3 SNAP type, the IP protocol type, or the TCP or UDP port
number. By default, the filters drop all protocol types except the NNL DIX
Ethernet type (hexadecimal 875B). Filters must be configured in all root
candidates and in any access point that can attach to the remote end of
an IP tunnel. You define the action, subtype, and value parameters in
customized filters.
Allow/Pass
Set the action to Allow or Pass. If you select Allow (checked), then
all frames of that type are passed. If you select Pass (unchecked),
then all frames of that type are dropped.
SubType
Selects the frame subtype you wish to filter.
Value
Specifies the value of the subtype. Refer to the following table for
the value for a specific subtype. The value must be two hex pairs.
You must enter port values as decimals; for example enter 23. for
Port 23. The access point displays the hexadecimal equivalent in
the Value field. When a match is found between frame subtype
and value, the specified action is taken.
To customize subtype filters, perform the following procedure:
1. From the Main Menu, select IP Tunnels then Tunnel Filters.
