IP and ARP frames are never forwarded inbound through an IP tunnel to
the root IP subnet unless the source IP address belongs to the root IP
subnet. (Frames are only forwarded inbound if the source IP address in
the IP or ARP frame identifies an end device that has roamed away from
its root IP subnet.) IP and ARP frames are never forwarded outbound
through an IP tunnel by the root access point unless the destination IP
address belongs to the root IP subnet. (Frames are only forwarded
outbound to end devices that have roamed away from the root IP subnet.)
For detailed information about other frame types that are never forwarded,
see “Frame Types That Are Never Forwarded” on page 146.
You can set the default action and scope for general and specific frame
types:
Allow/ Pass: Check or clear this check box. Check this check box to pass
all frames of the type. Clear this check box to drop all frames of the type.
Scope: Set scope to Unlisted or All. If you select All, then all frames of that
type are unconditionally passed or dropped, depending on the action you
specified. If you select Unlisted, then frames are passed or dropped only if
the frame type is not listed in the predefined or customizable tables.
