Total Access 600R User Interface Guide (UIG)
UDP Relay
This menu configures the 600R 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.
ROUTER>CONFIG>GLOBAL>BRIDGE
The
B
RIDGE
menu is used to set up the bridge parameters for the 600R. The bridging function runs at the
Media Access Control (MAC) level which allows any protocol packets that run over Ethernet to be for-
warded. 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. Default is
O
FF
.
Address Table
The 600R automatically maintains a table of MAC addresses detected and associates those addresses
with the LAN or WAN port from which they were received.
ROUTER>CONFIG>GLOBAL>SECURITY
Authentication
The method used for authenticating the PPP peer is selected here. The possible values are listed below.
MODE
When this option is set to
O
N
, the 600R will act as a relay agent.
Default is
O
FF
.
UDP R
ELAY
L
IST
Up to four relay destination servers can be specified in this list.
R
ELAY
A
DDRESS
This is the IP address of the server that will receive the relay packet.
Default is
0.0.0.0
UDP PORT TYPE
The choices are
S
TANDARD
(def) and
S
PECIFIED
. 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
S
PECIFIED
is set, the UDP port (1 to 65535) can be
specified in the UDP Port columns (up to three per server).
UDP P
ORT
1, 2, 3
Used for specifying UDP ports to be relayed. These fields only
apply when
UDP P
ORT
T
YPE
is set to
S
PECIFIED
. Default is 0.
AGING (0-65535)
The maximum time an idle MAC address remains in the table before
being removed. The value is in minutes. Range is
0 - 65535
. Default
is 5.
F
ORWARD
P
OLICY
When this parameter is set to
U
NKNOWN
(def), any bridge packet with
a destination MAC address that is not in the bridge table is forwarded
to all other ports (LAN and WAN). When set to
K
NOWN
, the packet
with the unknown destination MAC address is dropped and is not for-
warded.
N
ONE
(default) No attempt is made to authenticate the PPP peer.
R
ADIUS
The 600R will act as a RADIUS client and authenticate the PPP peer
using the RADIUS server. The Radius server parameters must be set up
properly for this to work.
PPP
The PPP profile is used to authenticate the PPP peer.
