128
ipaddr
IP address of the server to which the UDP packet will be forwarded.
first port
First port in the UDP port range to be created.
all Incorporates all the available UDP ports in the new range
last port
Last port in the UDP port range to be created
Example:
system addudprelay 192.168.1.5 all
SYSTEM ADMIN
Sets the administration password used to control write access to the target router configuration.
password
Write-enable login password
Example:
system admin adx1lp
SYSTEM AUTHEN
Forces the target router authentication protocol used for security negotiation with the remote routers when setting
the local side authentication. You should not need to issue this command as the best security possible is provided
with the
none
default.
none When set to
none
(the default), the authentication protocol is negotiated, with the minimum
best
security level as defined for each remote router in the database.
pap When set to
pap
, negotiation will begin with PAP (instead of CHAP) for those entries that have
PAP in the remote database and only when the call is initiated locally.
chap
Overrides all the remote database entries with
chap
; i.e., only CHAP will be performed.
Example:
system authen CHAP
SYSTEM BOOTPSERVER
Lets the router relay BootP or DHCP requests to a DHCP server on the WAN, when a PC attempts to acquire an
IP address using DHCP. This command disables the router’s DHCP server.
ipaddr
IP address of the target router in the format of 4 decimals separated by periods.
Example:
system bootpserver 128.1.210.64
system addUDPrelay
<ipaddr> <first port>|
all [<
last port
>]
system admin
<
password
>
system authen
none | pap | chap
system bootpServer <
ipaddr
