For the TFTP server, you can configure a TFTP directory and a value for TFTP Timeout and
Maximum Retransmissions. Set these values to 2 and 10 as shown.
The TFTP server can be disabled by clearing the Enable check box.
In the BootP section, you can select ARP mode: Dynamic or Static, and reply type:
Broadcast or Unicast. For a typical application, use Dynamic ARP mode and Unicast, as
shown above.
This option requires you to have administrator privileges otherwise an error message
appears. If you do not have administrator privileges, clear the ARP Manipulation Enabled
check box in the Preferences Window, Figure 63.
The Number of Timed Replies field (the number of initiated timed BootP replies) can be used
when the Gateway is installed behind a Firewall that blocks BootP broadcast requests. In a
typical application, this feature can be disabled by entering 0 in this field. When selected,
several BootP replies are sent to the Gateway immediately after the remote reset command.
