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.

RELAY ADDRESS

UDP PORT TYPE STANDARD (def)

SPECIFIED

UDP PORT 1, 2, 3

This is the IP address of the server that will re- ceive the relay packet.

The following standard UDP protocols are relayed when set: DHCP, TFTP, DNS, NTP (Network Time Protocol, port 123, NBNS (NetBios Name Server, port 137), NBDG (NetBIOS Datagram, port 138), and BootP.

When set, the UDP port (1 to 65535) can be specified in the UDP Port columns (up to three per server).

Used for specifying UDP ports to be relayed. These fields only apply when UDP PORT TYPE is

set to SPECIFIED.

Bridge

The 0￿￿ 2￿ 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.

AGING

FORWARD POLICY

The maximum time an idle MAC address remains in the table before being removed. The value is in min- utes.

When this parameter is set to ￿￿=￿￿<￿ (def), any bridge packet with a destination MAC address that is not in the bridge table is forwarded to all other ports. When set to =￿￿<￿, the packet with the un- known destination MAC address is dropped and is not forwarded.
