2.12.3 Setting the Discovery Addresses

By default, when or File | Open configuration is selected, Branch Gateway Manager's Select B5800 menu

appears. It performs a UDP broadcast to the address 255.255.255.255. This broadcast will only locate systems that are

on the same network subnet as the PC running Branch Gateway Manager.

The process above is called discovery. A UDP broadcast will not be routed to other networks and subnets. Therefore to

find systems not located on the same subnet as the Branch Gateway Manager PC, the following other options are

supported.

· Specific Addressing

The Unit/Broadcast Address shown on the Select B5800 menu can be changed to the specific IP address of

the required system. A single address is routable and so can be used to discover a system on another subnet.

· TCP Discovery Address Ranges

A set of TCP addresses and address ranges can be specified for use by the Select B5800 discovery process.

· Known System Discovery

Branch Gateway Manager can write the details of systems it discovers to a file. The list of systems in that file can

then be used for access to those systems. See Known System Discovery .

· DNS Lookup

Branch Gateway Manager can be configured to locate systems using DNS name lookup. This requires the systems

on a customer network to be added as names on the customer's DNS server and the Branch Gateway Manager PC

to be configured to use that server for DNS name resolution. The use of DNS is configured through File |

Preferences | Discovery .
