UDP Relay
This menu configures the Total Access 600 to act as a UDP relay agent for applications requiring a
response from UDP hosts that are not on the same network segment as their clients.
Mode
When this option is set to
ON
, the Total Access 600 will act as a relay agent.
UDP Relay List
Up to four relay destination servers can be specified in this list.
Bridge
The %
5,'*(
menu is used to set up the bridge parameters for the Total Access 600. The bridging function
runs at the Media Access Control (MAC) level which allows any protocol packets that run over Ethernet to
be forwarded. Bridging can run concurrently with IP. However, when IP routing is active, IP packets (which
include ARP packets) are not bridged.
Mode
This is used to enable the bridge function.
Address Table
The Total Access 600 automatically maintains a table of MAC addresses detected and associates those
addresses with the LAN or WAN port from which they were received.
