ICC
Distribution Mask:
The default value is 255.255.255.255, also known as the 2-
hop method. This ensures that packets can be successfully forwarded to the
target BBMD, which in turn will broadcast the packet on its own local subnet. If it
is necessary to change the default value, be sure to first check the capabilities of
the router. Not all routers support forwarding directed broadcasts.

Foreign Device Table (FDT)
The Foreign Device Table shows the foreign devices that have registered with
the BBMD. The web page must be refreshed to update the FDT.
IP Address:
IP address of the foreign device.
Port:
UDP port to receive BACnet/IP packets.
Time-to-Live:
The time (in seconds) within which a foreign device must re-
register.
Remaining:
The actual remaining time (in seconds) before the foreign device
entry is purged from the FDT if no re-registration occurs.

Submitting Changes
The “submit” button must be clicked in order to write changed settings to the
gateway’s filesystem.
Note that because these configuration elements are read from the filesystem only
when the gateway boots up, the act of submitting configuration changes will also
reset the gateway. Please allow 20 seconds for the gateway to reboot, at which
time it will then be operating with the recently-submitted configuration.
