Altum AC 600 User Manual LT-9064 Rev A 21
L2TP Server: Specifies the IP address of the remote
L2TP server.
Configure L2TP IP settings: Upon clicking the
“Configure...” button, the L2TP Common
Configuration page would be displayed. The protocol
DHCP client or Static address can be selected. The
corresponding options are explained within this
section (5.1.1 Common Configuration).
Advanced Settings
The following are options in the Advanced Settings
section tab. Some of these options are shown,
depending on the protocol being used.
Override MAC address: Allows you to specify a
different MAC address other than the radio's original
MAC address. This is useful if the ISP uses the MAC
address of a radio to identify a customer. Suppose
that the radio needs to be replaced. The new radio
can take on the MAC address of the previous radio in
order to continue having internet access.
Override MTU: Sets the maximum transmission unit
(MTU), the default being 1500 bytes. Unless, your ISP
requires, it is not recommended to change this setting.
Use gateway metric: Allows you to specify a gateway
metric. This acts as a cost for choosing the gateway
when a connected device has to select between
multiple available gateways. The gateway with the
smallest metric is chosen.
Use broadcast flag: When sending DHCP requests, a
client can indicate if it wants an answer in unicast or
broadcast, by setting the broadcast flag. This is
required for certain ISPs. Unchecked by default.
Use default gateway: Configures a default route.
Checked by default.
Use DNS servers advertised by peer: Uses the DNS
settings advertised by the DHCP server. Checked by
default.
Client ID to send when requesting DHCP: Sets the
identifier that may be required by the ISP or network
administrator. If not stated, the MAC address of the
client will be sent.
Vendor Class to send when requesting DHCP:
Identifies the vendor of a DHCP client for the
enhancement of vendor-specific DHCP functionality.
The following three options are specific to the PPTP
and PPPoE protocols:
LCP echo failure threshold: Sets the number of link
control protocol (LCP) echo failures before the peer is
presumed to be dead. Use 0 to ignore failures.
LCP echo interval: Specifies the interval in seconds to
send LCP echo requests. This is only effective in
conjunction with failure threshold.
Inactivity timeout: Sets the number of seconds of
inactivity, after which the connection is closed. Use 0
to persist connection.
Physical Settings
Interface: Chooses which physical interface to use for
the WAN zone. This can be the Ethernet Adapter
“eth0” or “eth1” that corresponds to each of the two
ports on the device for example. It could also be set
as the Wireless Network. If No Interface is selected, all
interfaces would be within the LAN zone.
Note: For boards with 2 ethernet ports, both
ports would be LAN ports in the default configuration.
You can still designate the WAN port in the firmware.
For s with power over Ethernet (PoE), only the port
further away from the DC Jack (right port) would be
the PoE input port (ethY). The port nearer to the DC
Jack (left port) would be the PoE output port (ethX).
5.2 Interfaces – LAN
5.2.1 Common Configuration
General Setup
Status: Shows a summary of the current LAN port
status, which includes uptime, MAC address, received
bytes and packets, transmitted bytes and packets, and
IPv4 address.
