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 nd 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 con gured 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 rst 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 rewall 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.

Bridging interface
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 rst DHCP client of the speci ed 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 con icts.
