Managing the broadcast interface

You can specify and display which router interfaces will receive UDP broadcasts to be forwarded.

To add a UDP broadcast interface:

  1. From the Device Manager menu bar, choose IP Routing > UDP Forwarding.
    2. The UDP_Forward dialog box opens.
  2. Click the Broadcast Interface tab.
    3. The Broadcast Interfaces tab opens.
  3. Click Insert.
    4. The UDP_Forward, Insert Broadcast Interfaces dialog box opens.
  4. In the LocalIfAddr text box, type a local interface IP address; or click the Addr button to select an address from the list.
  5. In the UdpPortFwdListId text box, type the forwarding list ID; or choose an ID from the list.
  6. In the MaxTtl field, type the maximum number of hops an IP broadcast can take from the source device to the destination device (the default is 4; the range is 1 to 16).
  7. In the BroadCastMask text box, enter the subnet mask of the local interface that is used for broadcasting the UDP broadcast packets.
    8. When configuring the UDP forwarding broadcast mask, the broadcast mask should be less specific (shorter in length) or equally specific (equal in length) to the subnet mask of the IP interface it is configured upon. If the UDP forwarding broadcast mask is configured to be more specific than the subnet mask of the corresponding IP interface, then UDP forwarding will not function properly.
