NB3000-Line-Hd User Manual 4.2
Attention:
You can have concurrent WWAN links which share a common recource like one
WWAN module using SIM cards of different providers. In that case it would
not be possible to find out if the link with the higher priority is available with-
out putting down the low priority link. Therefor such a link will behave like a
switchover
even if configured as
permanent
.
For mobile links, it is further possible to pass through the WAN address towards a local host
(also called Drop-In or IP Pass-through). In particular, the first DHCP client will receive the
public IP address. More or less, the system acts like a modem in such case which can be
helpful in case of firewall issues. Once established, the Web Manager can be reached over
port 8080 using the WAN address but still over the LAN1 interface using port 80.
Parameter WAN Link Operation Modes
disabled Link is disabled
permanent Link is being established permanently
on switchover Link is being established on switchover, it will be dialled if pre-
vious links failed
distributed Link is member of a load distribution group
Parameter WAN Link Settings
Operation mode The operation mode of the link
Weight The weight ratio of a distributed link
Switch-back Specifies the switch-back condition of a switchover link and the
time after an active hotlink will be teared down
Bridging interface
1
If WLAN client, the LAN interface to which the WAN link should
be bridged.
NetModule routers provide a feature called IP pass-through (aka Drop-In mode). If enabled,
the WAN address will be be passed-through to the first DHCP client of the specified LAN
interface. As Ethernet-based communication requires additional addresses, we pick an ap-
propriate subnet to talk to the LAN host. In case this overlaps with other addresses of your
WAN network, you may optionally specify the network given by your provider to avoid any
address conflicts.
Parameter IP Pass-Through Settings
IP Pass-through Enables or disables IP pass-through
1
This options requires an Access Point with four address frame format support.
